started rebuilding level one
added platforms to level
added squirrel
more squirrel logic
fixed squirrel bug by overwriting preUpdate (on the first sprite preUpdate, it was using its parent's (world's) position to calculate its own position, which caused it to be screwed up because the game.camera.follow on player causes world X to have a negative value

changed enemy generation to be more clear
Added more stuff to level
using groups now for handling enemies. did some hacking around to make sure that squirrels and projectiles that go offscreen get recycled.
