Fixes Space-Ruin Issues (#6404)

* Fixes Space-Ruin Issues

Fixes Load-Time and Lighting issues on the Space Ruins by moving the loading of the ruins into Atlas

* Reworks the space ruin loader

It´s now based on a json file which allows to set the weight of the ruins, add various tags with a specified weight and restrict the maps the ruin can be used in

* Fixes compile warnings

* Change z-levels in aurora.dm

* Moves the SubSystem

* Changes the player_levels back again since the away mission is now loaded after the z expansion
