Now with better AI!

Since Ludum Dare I've improved a few things so that Cotton Candy Dreams works better. 

Bug Fixes:

• Changed AI for fairies so they stop falling out of world. 
  Moved trees so they aren't floating. 
  Adjusted some landscape so the player stops falling out of the world.
  Added collision boxes to portal so player does not fly through it.
  Changed crystal pick ups so they are actually floating instead of just sitting in the air.
  Removed some of the clutter to help performance.
