Achievements!

Achievements are now enabled.
Because of the method of wrapping the flash games, it's a slightly awkward system, you may find that achievements don't award at the right times sometimes
They'll likely award when you return to the main screen, the men,u or flip between screens. This is a result of the nature of the flash games and their achievement trackers
I've enabled only a few for now; there will be more to come soon. It's a long process to add them for each game.
