Fixed lost cave teleporters, however...

i figured how to fix the teleporters as i was laying down to go to sleep
so (naturally) i had to get up and fix it, but upon getting it working i
quickly found it its just way, WAY to complicated to implement. Look at
the obj_player_spawner, the goto_parent, and the lost cave teles to see
what i've done. its just too unmanageable but maybe it will give you
some ideas as how to fix it.
