Source one shaders fixes and additions, new skin group saving method

[hisprofile]

Better Materials

(left is new, right is old)

• Shader Fixes/Additions
  • VertexLitGeneric
  • Received Lightwarp support (see the cel shading on Heavy's skin)
  • Better transparency and additive implementation (see the glow on Bolt Boy cosmetic)
  • Less broken paint regions (see the Bolt Boy cosmetic)
  • UnlitTwoTexture
  • Better implementation (see the sun beams and the capture point holograms)
  • Modulate shader added
• Shader General
  • Shader name and vmt parameters are stored as custom properties for materials
  • dx90 parameters are unraveled and saved into the main parameters instead

    mdl porting

• .mdl importing
  • Changed the skin group saving method to save the actual material IDs instead of their names
  • REDxEYE, I swear the only way this could be implemented was to use a pseudo-pointer for materials. Using from the buffer never worked, so I used a uuid4 string instead. It works?
