NAME
	add_room_object - register a room object with the MapD

PROTOTYPE
	void add_room_object(object room)

CALLED BY
	System, Common, Game

DESCRIPTION
	Registers a room object with MapD.  The room does this for itself
	when its create() function is called.  Any room that doesn't, but
	that is later added to MapD, will generate an error.

	This does not assign a room number to the room, it simply makes
	sure that the MapD has seen the room at least once.

RETURN VALUE
	None.

ERRORS
	Registering an already-registered room will cause an error.
