Solas Shader

Features added/changed:

+ Reworked Aurora Borealis. Visually there shouldn't be many differences, however you can now actually fly through it. The default altitude is 50k blocks Y
+ Improved volumetric clouds shaping and lighting
+ Completely reworked the entire PBR system. It now works on entities and held objects and is closer to the LabPBR standart than the previous implementation.

Features fixed:

- Fixed incorrect translucency blending with Voxy and Distant Horizons LODs
- Fixed many errors with PBR
- Fixed time being frozen on newest versions
- Fixed Colorwheel compatibility
- Fixed compilation errors when changing stars amount or disabling SSAO
