Crates, Players, and Enemies now get their block size dynamically
Creatures now check the foreground of the current tile while moving.

Part of #41

TODO: The tile images seem to not map properly to the screen. This
should be fixed.
fixed enemy player collision to throw the player back in the direction the enemy is facing
Removed all instances of 'import *' from the codebase

The one exception is 'from pygame.locals import *' since that's
recommended.

Don't use 'import *' unless you want to make me cry.
Fixed a bug where the number of tiles stored internally differed from
the number of tiles in the maps.
