 These are the changes to eliminate most of the arbitrary limits in the
system, such as the maximum number of messages in a room, or the maximum
number of messages in a user mailbox.

 The only remaining arbitrary limits are the number of room slots in the
system (MAXROOMS) and the number of floor slots (MAXFLOORS).  I don't know if
we'll be able to nix those.

 Right now, rooms and mailboxes will grow infinitely.  We now have to impement
artificial constraints.
