DROP-TOs
When the @link command is used on a room, it sets a drop-to location. Any
object dropped in the room (if it isn't STICKY) will go to that location. If
the room is STICKY, the drop-to will be delayed until the last person in the
room has left.  Whenever objects are dropped in a room, the @odrop
message is displayed (preceded by the object's name), to everyone in the room.
