no-teleport-to property option

i'd like to see a no-teleport-to option for land i own. if it's turned on, a person trying to teleport to a landmark on my land(or home if they set home on my land) will teleport somewhere near my land, but not on my land. this would keep people from popping into our home if we wish, or from *bypassing a ticket counter at a paid attraction*.

or optionally, make llTeleportAgentHome(); teleport the Agent off the owner's land he is currently on even if he has set home to there. sorry if it already does that, i haven't tested it yet.
