Level Editor

Started and finished the level editor, which great results. I've had a surprising amount of fun just goofing off creating levels (it's like pixel art, only... not). Here are a few examples.

Made some changes to the wall code - walls are now rendered separately and are added to the pymunk space as static objects. This brought my fps on the maze level (HEAVY on the walls) from 4 back up to the cap of 30.

Here is a screenshot of the maze level. Imagine doing this without the level editor… **shudder**
