- 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)
