New Render system 10% complete

Two blocks transitioned to new system. I've been coding for 12 hours
solid (including FlenixCities) so sleeping now.
Total overhaul, 90% complete.

I still need to do:
- Names
- Fix the rendered things for the new build-by-block system
- Add Ghost blocks for the ramps
- Icon textures (I have them, just not implemented)
