VertexLitGeneric rewrite

VertexLitGeneric is the shader most commonly used to render models.

$bumpmap: Bumpmapping.
$color2: Color tinting.
$detail: Detail texturing.
$envmap: Specular reflections.
$emissiveblend: Advanced flowing self-illumination, used on the Vortigaunts in Episode 2.
$flesh: The flesh effect used for Alyx in Episode 2.
$halflambert: Half-lambertian shading.
$lightwarptexture: Per-texel color modification using a warp texture.
$phong: Diffuse reflections.
$rimlight: Constant rimlight based on phong and ambient lighting.
$selfillum: Self-illumination.
$translucent
$alpha: Expensive and cheap transparency.
$compress
$stretch: Wrinklemaps for character faces.
$treeSway: Vertex manipulation to give the effect of trees swaying in the wind.

$albedo <texture>: Todo: albedo (Base texture with no baked lighting)
$desaturatewithbasealpha <float>: Use the base alpha to desaturate the base texture. Set to non-zero to enable, value gets multiplied into the alpha channel before desaturating.
$flashlightnolambert <bool>: Todo: Flashlight pass sets N.L=1.0
$seperatedetailuvs <bool>: Todo: Use texcoord1 for detail texture
$vertexfog: Todo: What does this do? Found in L4D2 materials.

VertexLitGeneric natively supports the Spy cloak effect from Team Fortress 2. You will want to combine it with a sine wave proxy for the full effect.

$cloakpassenabled <bool>: Enables cloaking effects.
$cloakfactor <normal>: 0 = fully visible, 1 = fully invisible.
$cloakcolortint <RGB matrix>: Colours the refraction effect. Default is white.
$refractamount <float>: How strong the refraction effect should be when the material is partially cloaked (default = 2).

LightmappedGeneric is the shader most commonly used to render brushes and other lightmapped surfaces.
