Trims back wilderness code that was dependent on tether map.

* Reverted random.dm back to Polaris as there is no need for the VOREStation customs.
* Fixed /obj/random/outside_mob so it will actually work (You can't set vars on a type!)
* Removed all wilderness code outside of the tether map.  It was only setting life_disabled on mobs spawning there. We can do that with a subsystem or by dynamic maploading instead.
