							DOORS

doorobjlist[] holds most of the information for the doors

doorposition[] holds the amount the door is open, ranging from 0 to 0xffff
	this is directly accessed by AsmRefresh during rendering

The number of doors is limited to 64 because a spot in tilemap holds the
	door number in the low 6 bits, with the high bit meaning a door center
	and bit 6 meaning a door side tile

Open doors conect two areas, so sounds will travel between them and sight
	will be checked when the player is in a connected area.

Areaconnect is incremented/decremented by each door. If >0 they connect

Every time a door opens or closes the areabyplayer matrix gets recalculated.
	An area is true if it connects with the player's current spor.
