[crossfire] Apartment connections

[Preston Crow]

Here's an idea I've had floating around for a while:

There are a number of teleporters in the game to take players from city
to city, including many in apartments.  I was thinking that it might be
better to instead of having teleporters to cities in the apartments, to
have each apartment have a gateway into a room that they all share.  You
would have to pay a price to get access to this room from any given
apartment, but eventually, you could get all your apartments connected.

This would probably be implemented by having something in each apartment
where you could buy a pair of keys, one of which would open a door
letting you get to a teleporter, and one which would open the door on
the other side of the teleporter in the gate room.

Of course, the cost of the keys could be a combination of cash and quest
items, with higher prices for the more important locations (e.g., Pup
Land).

The two downsides of this are that it would require some tricky
conversion to switch over current apartments when upgrading servers, and
the problem would arise again as more apartments are added to the game.
