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.
