pylint fixes.

When clicking a link in a message viewed in HTML mode, if the link represents a data blob, launch a "Save File" dialog and write the file directly, rather than opening the link in an external browser.
Add "Attach File" button to message composition.

+PyBitmessage(Android)
+
+This sample aims to be as close to a real world example of a mobile. It has a more refined design and also provides a practical example of how a mobile app would interact and communicate with its addresses.
+
+Steps for trying out this sample:
+
+Compile and install the mobile app onto your mobile device or emulator.
+
+
+Getting Started
+
+This sample uses the kivy as Kivy is an open source, cross-platform Python framework for the development of applications that make use of innovative, multi-touch user interfaces. The aim is to allow for quick and easy interaction design and rapid prototyping whilst making your code reusable and deployable.
+
+Kivy is written in Python and Cython, supports various input devices and has an extensive widget library. With the same codebase, you can target Windows, OS X, Linux, Android and iOS. All Kivy widgets are built with multitouch support. 
+
+Kivy in support take Buildozer which is a tool that automates the entire build process. It downloads and sets up all the prerequisite for python-for-android, including the android SDK and NDK, then builds an apk that can be automatically pushed to the device.
+
+Buildozer currently works only in Linux, and is an alpha release, but it already works well and can significantly simplify the apk build.
+
+To build this project, use the "Buildozer android release deploy run" command or use.
+Buildozer ue=sed for creating application packages easily.The goal is to have one "buildozer.spec" file in your app directory, describing your application requirements and settings such as title, icon, included modules etc. Buildozer will use that spec to create a package for Android, iOS, Windows, OSX and/or Linux.
+
+Installing Requirements
+
+You can create a package for android using the python-for-android project as with using the Buildozer tool to automate the entire process. You can also see Packaging your application for the Kivy Launcher to run kivy programs without compiling them.
+
+You can get buildozer at https://github.com/kivy/buildozer or you can directly install using pip install buildozer
+
+This will install buildozer in your system. Afterwards, navigate to your project directory and run:
+
+buildozer init
+
+This creates a buildozer.spec file controlling your build configuration. You should edit it appropriately with your app name etc. You can set variables to control most or all of the parameters passed to python-for-android.
+
+Install buildozer’s dependencies.
+
+Finally, plug in your android device and run:
+
+buildozer android debug deploy run >> To build, push and automatically run the apk on your device. Here we used debug as tested in debug mode for now.
+
+Packaging your application for the Kivy Launcher

+pybitmessage (0.3.0-1) raring; urgency=low
+
+  * Added new API function: getStatus
+
+  * Added error-handling around all sock.sendall() functions
+    in the receiveData thread so that if there is a problem
+    sending data, the threads will close gracefully
+
+  * Abandoned and removed the connectionsCount data structure;
+    use the connectedHostsList instead because it has proved to be
+    more accurate than trying to maintain the connectionsCount
+
+  * Added daemon mode. All UI code moved into a module and many
+    shared objects moved into shared.py
+
+  * Truncate display of very long messages to avoid freezing the UI
+
+  * Added encrypted broadcasts for v3 addresses or v2 addresses
+    after 2013-05-28 10:00 UTC
+
+  * No longer self.sock.close() from within receiveDataThreads,
+    let the sendDataThreads do it
+
+  * Swapped out the v2 announcements subscription address for a v3
+    announcements subscription address
+
+  * Vacuum the messages.dat file once a month:
+    will greatly reduce the file size
+
+  * Added a settings table in message.dat
+
+  * Implemented v3 addresses:
+    pubkey messages must now include two var_ints: nonce_trials_per_byte
+    and extra_bytes, and also be signed. When sending a message to a v3
+    address, the sender must use these values in calculating its POW or
+    else the message will not be accepted by the receiver.
+
+  * Display a privacy warning when selecting 'Send Broadcast from this address'
+
+  * Added gitignore file
+
+  * Added code in preparation for a switch from 32-bit time to 64-bit time.
+    Nodes will now advertise themselves as using protocol version 2.
+
+  * Don't necessarily delete entries from the inventory after 2.5 days;
+    leave pubkeys there for 28 days so that we don't process the same ones
+    many times throughout a month. This was causing the 'pubkeys processed'
+    indicator on the 'Network Status' tab to not accurately reflect the
+    number of truly new addresses on the network.
+
+  * Use 32 threads for outgoing connections in order to connect quickly
+
+  * Fix typo when calling os.environ in the sys.platform=='darwin' case
+
+  * Allow the cancelling of a message which is in the process of being
+    sent by trashing it then restarting Bitmessage
+
+  * Bug fix: can't delete address from address book

+
+pybitmessage (0.2.8-1) unstable; urgency=low
+
+  * Fixed Ubuntu & OS X issue:
+    Bitmessage wouldn't receive any objects from peers after restart.
+
+  * Inventory flush to disk when exiting program now vastly faster.
+
+  * Fixed address generation bug (kept Bitmessage from restarting).
+
+  * Improve deserialization of messages
+    before processing (a 'best practice').
+
+  * Change to help Macs find OpenSSL the way Unix systems find it.
+
+  * Do not share or accept IPs which are in the private IP ranges.
+
+  * Added time-fuzzing
+    to the embedded time in pubkey and getpubkey messages.
+
+  * Added a knownNodes lock
+    to prevent an exception from sometimes occurring when saving
+    the data-structure to disk.
+
+  * Show unread messages in bold
+    and do not display new messages automatically.
+
+  * Support selecting multiple items
+    in the inbox, sent box, and address book.
+
+  * Use delete key to trash Inbox or Sent messages.
+
+  * Display richtext(HTML) messages
+    from senders in address book or subscriptions (although not
+    pseudo-mailing-lists; use new right-click option).
+
+  * Trim spaces
+    from the beginning and end of addresses when adding to
+    address book, subscriptions, and blacklist.
+
+  * Improved the display of the time for foreign language users.

+
+  * Added debian packaging
+
+  * Script to generate debian packages
+
+  * SVG icon for Gnome shell, etc
+
+  * Source moved int src directory for debian standards compatibility
+
+  * Trailing carriage return on COPYING LICENSE and README.md

+Description: Send encrypted messages
+ Bitmessage is a P2P communications protocol used to send encrypted
+ messages to another person or to many subscribers. It is decentralized and
+ trustless, meaning that you need-not inherently trust any entities like
+ root certificate authorities. It uses strong authentication which means
+ that the sender of a message cannot be spoofed, and it aims to hide
+ "non-content" data, like the sender and receiver of messages, from passive
+ eavesdroppers like those running warrantless wiretapping programs.

-`XML-RPC <http://xmlrpc.scripting.com/spec.html>`_ or
-`JSON-RPC <https://www.jsonrpc.org/specification>`_ like in bitcoin.
-It's selected according to 'apivariant' setting in config file.
-
-Special value ``apivariant=legacy`` is to mimic the old pre 0.6.3
-behaviour when any results are returned as strings of json.
-
-.. list-table:: All config settings related to API:
-  :header-rows: 0
-
-  * - apienabled = true
-    - if 'false' the `singleAPI` wont start
-  * - apiinterface = 127.0.0.1
-    - this is the recommended default
-  * - apiport = 8442
-    - the API listens apiinterface:apiport if apiport is not used,
-      random in range (32767, 65535) otherwice
-  * - apivariant = xml
-    - current default for backward compatibility, 'json' is recommended
-  * - apiusername = username
-    - set the username
-  * - apipassword = password
-    - and the password
-  * - apinotifypath =
-    - not really the API setting, this sets a path for the executable to be ran
-      when certain internal event happens
-
-To use the API concider such simple example:
-
-.. code-block:: python
-
-    import jsonrpclib
-
-    from pybitmessage import bmconfigparser, helper_startup
-
-    helper_startup.loadConfig()  # find and load local config file
-    conf = bmconfigparser.BMConfigParser()
-    api_uri = "http://%s:%s@127.0.0.1:8442/" % (
-        conf.safeGet('bitmessagesettings', 'apiusername'),
-        conf.safeGet('bitmessagesettings', 'apipassword')
-    )
-    api = jsonrpclib.ServerProxy(api_uri)
-    print(api.clientStatus())
-

+#
+#[app@demo]
+#title = My Application (demo)
+#
+#[app:source.exclude_patterns@demo]
+#images/hd/*
+#
+#    Then, invoke the command line with the "demo" profile:

+Bottom Sheets
+=============
+
+`Material Design spec Bottom Sheets page <http://www.google.com/design/spec/components/bottom-sheets.html>`_
+
+In this module there's the :class:`MDBottomSheet` class which will let you implement your own Material Design Bottom Sheets, and there are two classes called :class:`MDListBottomSheet` and :class:`MDGridBottomSheet` implementing the ones mentioned in the spec.
+
+Examples
+--------
+
+.. note::
+
+    These widgets are designed to be called from Python code only.
+
+For :class:`MDListBottomSheet`:
+
+.. code-block:: python
+
+    bs = MDListBottomSheet()
+    bs.add_item("Here's an item with text only", lambda x: x)
+    bs.add_item("Here's an item with an icon", lambda x: x, icon='md-cast')
+    bs.add_item("Here's another!", lambda x: x, icon='md-nfc')
+    bs.open()
+
+For :class:`MDListBottomSheet`:
+
+.. code-block:: python
+
+    bs = MDGridBottomSheet()
+    bs.add_item("Facebook", lambda x: x, icon_src='./assets/facebook-box.png')
+    bs.add_item("YouTube", lambda x: x, icon_src='./assets/youtube-play.png')
+    bs.add_item("Twitter", lambda x: x, icon_src='./assets/twitter.png')
+    bs.add_item("Da Cloud", lambda x: x, icon_src='./assets/cloud-upload.png')
+    bs.add_item("Camera", lambda x: x, icon_src='./assets/camera.png')
+    bs.open()
