Major Update for Cable Rendering.

TESRs will are no longer used if the tile contains no dynamic renders.
Added alpha pass rendering for stained glass.
Enabled Stained Glass facades.
Cables / Facades have less geometry by hiding faces on connected boxes.
Added AlphaPass Option to disable AlphaPass Cables rendering ( fixes crash with Immbis Microblocks. )
