Merge branch 'game-integration' into socketio-game
Further integration of server with client ui. Users can now invite other users to play a game. If they accept, their client waits for the host users to start the game, which triggers the transition to the session view for all players that accepted the invite. The next step is to get Pong working again with the new socket.io implementation.
Replaced the stored game id with the game name, since game names will be set by admins and will be unique.
