Global Illumination Outside of Station

[cosmiccoincidence]

Summary

There should be a global illumination outside the station.

Goal

The goal here is so you can see your player and items outside the station as well as structures with no roof (tiles w/o a plenum).

So basically any tile that doesn't have "Plenum" as the base tile layer should have global illumination.

The global illumination should only impact areas OUTSIDE of structures (any tile without a plenum).
