First attempt to normallize DB - BROKEN
Write database information to a txt file

 - Mostly working
 - Increment isn't working very intelligently for create_user() -- can overwrite another user's information if they have the same session id
Delete .pyc
Merge db & dynamic class creation & game -> class
Text file used as database

 - Problem where two different users with the same id can overwrite the other's information is fixed (hopefully)
 - Works when two different uses connect from two different browsers!
Update tests, docstrings
