DOORS
doorobjlist[] holds most of the information for the doors
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.
