Handling doors and rooms placement during quest generation

[MarcCote]

If we want to generate doors and rooms as needed during quest generation, we will need to re-think the way we position doors/rooms. Right now, we are assuming symmetric connections between the rooms, maybe we should allow "bends" in the connections e.g.

           RoomB
                 |
RoomA ---/

Also, we might want to consider doors as rooms, i.e. they have exits too (back/front of the door).
