Combine UserContext and GameContext under one AppDataContext.

Change all references to UserContext and GameContext.
Add AppDataContext connection to web.config (maybe unnecessary as DefaultConnection is set to our database).
Add RiskController and views.
Add BlackJackController and views.
Delete some unnecessary initialization file.
Conclusion:
Entity up and running.
Database ready to go.
