Add Joust to preloaded Apps
We currently don't have any games in the preloaded games, lets fix it!
After publishing 'Joust' to the app store I've seen it played by people without my prompting twice, and it's a group game so getting everyone to install it is a huge barrier to entry.
We should make it a phenomenon for tomorrow night!
