Patch "Push".1

The following things have been added or changed:

• Your progress is now saved in browser! Keep in mind that the save system might still get moved around as development progresses and part of your progress (if not all) could possibly be erased. Note that clearing cache or cookies might also remove your progress!
• Fixed a bug where the player could move into the void of "PushThru" (the level).
• Fixed a bug where a door "stuck" between two walls, would not "unstuck" itself after another door was pushed into either wall and then opened until the player undoes a move. (Doors that became "stuck" by being pushed into a wall tile are not affected).
