Finally got cubemaps working

Added electrical substation and power lines, Added reversing loop to Surface Yard and made main drag single track, made the cliff path actually useful, added some new stations, changed some crossovers to single crossovers, added cubemaps (knock on wood)

Expanded the underground, added a second yard, added 3d skybox, added new passenger station(s), added more build garages, did some optimization, improved some switches

Added glowing crystal materials to material tool... hopefully.

Separated the track models into a second workshop file

Redid the entire map. Major improvements in the areas of render control, track layout, terrain.

Fixed the double wyes, for real this time

(Hopefully) fixed the double wye problem, made the crossovers more forgiving

Overhauled the entire map. Built the surface from scratch to render less of the map at once, expanded greatly on the underground portion. There are a lot of Dev textures now but this is just a proverbial bone I'm throwing to the proverbial dogs because I'm anxious to see how the new setup performs.

Added the first stage of the underground rail network, made one of the hills marginally less steep, made the turntable slightly better
