Splitting up files

[miketwo]

How do you feel about the next thing being splitting up the files so we can work on it at the same time with less merge conflicts?

Maybe:

• All Cards in one file
• All Potions in one file
• All Relics in one file
• All Effects in one file
• Helpers:(Displayer | Generator | EffectInterface) --> 3 separate files
• Player and Enemy --> separate files
• Different encouters (combat|rest|shop|unknown) --> separate files
