Water world!

The gameplay for the water world is almost done and Gnapp's tiles look phenomenal. This was super fun to code!

We've had to cut back a bit on the features, there were going to be spells and stuff you gain from spending time at a world that you can use elsewhere but I think that would just add too much complexity. I figure it's best to focus on making the three worlds fun and the game feel hectic rather than add more features.
