Add stuff to z5

[poland spring]

Right now the Oshan trench is chock full of goodies to find and explore whereas sometimes you just can't find anything cool on z5!!!  So if you have any debris or asteroid or whatever maps lying around just plug em into z5, it's usually so much open space and normal asteroid that any amount of flavor would make it more fun (ESPECIALLY FOR THE RP SERVER WHICH IS ALMOST NEVER ON OSHAN)
