	Doors are similar to buttons, but can spawn a fat trigger field
	around them to open without a touch, and they link together to 
	form simultanious double/quad doors.
 
	Door.owner is the master door.  If there is only one door, it 
	points to itself. If multiple doors, all will point to a single 
	one.

	Door.enemy chains from the master door through all doors linked 
	in the chain.
