Transitioning to Pyglet

Moved some things, get rid of things, tried to start transition to
Pyglet from Pygame. I've also begun coding the map generator.
Map Generation Tinkering

Added a more intricate (yet equally crappy) map generator using random
cells dependent upon adjacent cells. Also changed name of Environment.py
to EnvironmentObsolete.py to signify its being deleted (once I get
around to fixing Application.py)
