EXAMPLES: Add pymunk example
DOCS: update
TILESET: Add stand-in tileset until I can make my own
MAIN: Add python extension to game
INSTALL: Add requirements
MAPS: Initial map loading

This is a big work in progress.  I need to find a good place to put
the controller logic for loading maps, and need to get all tiles
on the map as objects that have their update called, and well as
collision areas and a bunch of other stuff.
