- fixes "fast python" (multiprocessing) PoW
- python PoW (both slow and fast) interruptible on *NIX
- signal handler should handle multiple processes and threads correctly
(only tested on Linux)
- popul window asking whether to interrupt PoW when quitting QT GUI
- PoW status in "sent" folder fixes and now also displays broadcast
status which didn't exist before
- Fixes#894
- handles old dialog versions better if using curses
- can spawn SMTP delivery thread if configured (only when in daemon
mode)
- daemonized mode now works more like it's properly supposed to on unix
(double fork etc). You may have to adjust your init scripts, when
when using upstart for example you should now use "expect daemon"
- daemon mode now cleanly shuts down when TERM/INT signal is received
When advertising nodes and when establishing connections, private IP
range checks were not done. This could cause private IPs to be
advertised across the network. Also, some of the checks weren't
IPv6-aware.
Fixes Bitmessage#768
