Add UserModel and UserEntityManager

This adds the user model and entity manager for the user model, this will be used to keep the contact information for the user (email, IM, SMS).

I also made a slight change in the PlanningPokerEntityManager so it only pulls the games from the current project.

CreateGameView only sends email if StartNow is checked
I also 'implemented' email notification into NewGameView, but it was technically already there because NewGameView is just a copypasta of CreateGameView.

Sending the close notification upon a deadline closing is still coming.

And there was a bug fix to stop email address duplication in manual game closing
