working on pgn
have to finish implementing game#make_pgn so that I can delete the model in backbone when checkmate is true, which will make a delete request and call the destroy action, which will create a pgn from the game and delete the game, then finally return the pgn to the game via pusher, and this will trigger a results page with will have rediect buttons
clock hack
adds pgn model, pusher triggers for game#update action, deletetion of game and creation of pgn upon checkmate, backbone view for results page, and display of past games on user profile.
