- Added .gitattributes and .gitignore files
- Simplified player model, really only used to ensure the name hasn't been taken as of now. Can put player specific info on it later
- Added a Score entity that will hold scores for each player and game
- Added a Debtentity that will hold the amount that one player owes another for a game (this may not be needed, maybe just calculate this on the fly...)
- Added some functionality to calculate owings for a game from the Debts

Note: I haven't tested these changes yet
