QUEUE version 0.5 rev 1 ~ Minor tweaks

What changed:

0.5 rev 1 - 		Made the sprite bigger, yes. Made them nice, not really ...
		I need to polish the sprites before releasing a nice demo,
		for now, feast your eyes on chunky sprites.
	  -	FIXED: Doors now open and close, really.
	  -	NEW: Door and stair is under one PNG and quad.
	  -	BUGS: Still same bugs.

Demo for 0.5 will now be available, when it's really done. I just need to
make proper sprites and fix some bugs.
