Add team members to the game

[Carkzis]

• On the team screen, you can add players to the game.
• List of players to add will come from a fake database, add a random player for now using a button.
• Players within a game are inserted into the local database.
• Cap of 4 players, adjustable.
• List of players displays on the screen.
• Entering a different game will have a different list of players.

Have used an association of two tables, many to many for users and games.

Need to:

• Write tests for the TeamDao.
• Have it so inserting a user into the team dao also adds the game they are part of (perhaps insert a cross reference, see insertOrIgnoreTopicCrossRefEntities in nowinandroid, and PopulatedNewsResource).

And then all the rest.
