91F2: An ordinary door
Used by the routines at TIMED_DOOR_OPEN and DOOR_SERF.
The plain doorway, and the routine every other kind falls back on once it has decided to let the player through. It offers $1111 as the tolerance, asks PLAYER_AT_DOOR whether anyone is standing in it, and calls ENTER_ROOM if so -- then draws itself either way.
