JUMP_OK
@set me=jump_ok, @set here=jump_ok.  On people, this allows other people
to teleport you.  In rooms, it allows teleportation.  On things, it allows
anyone to teleport the objects.  It has no meaning for exits.  Teleportation
is also allowed in rooms you own.  Teleportation must be allowed in the
destination and in the room you are in, or else it may not be permitted.
