PySokoban - 0.9-r1

A Sokoban game written in python for the Google Highly Open Participation Contest. It plays exactly like any other sokoban game - http://en.wikipedia.org/wiki/Sokoban.

A couple of bug fixes related to game saving and loading: * Fixed bug where artifacts from the previous level were left when loading a saved game. * Fixed bug where goal count from the previous level was not updated. This led to the level ending prematurely or too late.
