Added many shader source files
This should include the latest version of every shader that was in the
2007 SDK. It also includes a smattering of debug shaders, both VR
distortion shaders, and other assorted shaders that will hopefully be
useful.
None of these new files are included in the game shader DLL project. If
you need to modify one of these shaders for use in your mod you will
need to rename it so that you don't collide with the version of that
shader that lives in stdshader_dx9.dll.

+; This shader takes:
+; t0 = normal map
+; t1 = base texture
+; v0 = directional light color
+; t2 = directional light direction (biased into 0-1)
+; c0 = percent of dirlight to add as ambient
+;
+; Output:
+; (t0 dot t1) * v0

+tex t0 ; Get the 3-vector from the normal map
