~ Reworked shader parameters on some materials.
+ Added more keywords to a wall texture.
- Cleaned up useless parameters in some materials.
+ Added $alphatest to materials with severe aliasing issues (for those who use transparency supersampling).
~ Boosted phong on more materials.
~ Disabled culling on some PHX train (pack2) materials.

~ Cubemaps now show properly on the toolgun screen.

+ Enhanced 2 grass materials.
~ Boosted phong on one concrete texture.

+ Re-added $blendmodulatetexture due to the incompatibilty with $detail being fixed. Note that the time of writing, the Garry's Mod update isn't available yet.

~ Reworked some materials to use new methods and be more physically accurate.
- Removed $halflambert from PHX glass.

This update adds more keywords to some of the map materials for easier searching in Hammer. Refer to an online guide for getting the materials into Hammer. Keywords include, but are not limited to: interior, exterior, nature, ground, wall, etc.

+ Added more keywords for some world materials.
~ Quadrupled phong on the physics gun.

~ Increased phong on some more materials.
~ Normalized the color for construct_concrete_ground_bright.
~ Disabled culling for more displacement materials.
~ Adjusted phong on some materials.
~ Fixed a reflection issue on the PHX chess board.

~ Quadrupled phong intensity for some of the materials.
~ Adjusted phong on construct walls and grass.
~ Disabled culling for some construct grass materials.
~ Normalized color for a grass material.

~ Reordered parameters in a few more materials.
~ Reworked reflections for default HEV hands and grenade worldmodel.
~ Disabled culling on default HEV hands.
+ Enhanced toolgun screen. The screen illuminates a little darker and it now has reflections. Cubemap reflections are janky and only work properly on some custom tool screens, but phong works perfectly.

~ Reordered parameters for many VMTs.
~ Adjusted phong and rimlight on a few materials.
~ Reformatted a few one line VMTs.
~ Made capitalization consistent in many VMTs.
~ Disabled half-lambert for even more materials using phong.
~ Optimized the file size of some VMTs.
~ Replaced some spaces with tabs.
~ Corrected rimlight exponent for some materials.
~ Changed a tree material from UnlitGeneric to VertexLitGeneric.
~ Fixed models/onfire not having phong.
~ Fixed stretched blending on gm_construct/grass-sand_13 by removing $blendmodulatetexture.
