Outlines light support & HDR lighting support

• Outline now integrated into the lighting system
• vertex lights input added (needs work for a better toony style)
• optimization for outlines overdraw. Do not recommend outlines on transparency shaders.
• somewhat better transparency support for light sources
• outline fixes for mirrors and scaling thickness by distance
• light inputs now HDR. Shader will go to emission by light sources
• shader emission can come from combining outlines, shine, additive matcap, etc.
• shadow light attenuation fixes (this code will always change!), much better toon ramps
• fixed cases of bad face normals causing emission on the model
• rewriting the code away from shaderforge nodes into human readable
• something else missed that the commits will say...
