Python 2 port

Numerous parts of the code are currently coded for Python 3. It should finish being ported to Python 2.

I'm running your program with Python 2, and it seems to be working fine. Any specific bugs you've noticed?

I don't believe I ever completely finished porting over certain sections in Tkinter. So it should not outright crash if run in Python 2, but not all GUI functionality will be there. If everything is actually working correctly, I'd be surprised but pleased.
