Inventory refactoring
- minor refactoring, made it into singleton instead of a shared global
  variable. This makes it a little bit cleaner and moves the class into
a separate file
- removed duplicate inventory locking
- renamed singleton.py to singleinstance.py (this is the code that
  ensures only one instance of PyBitmessage runs at the same time)
