Create runtime code for generating Quake 3 Shader file for all model assets with alpha translucency

[MotoLegacy]

Describe your suggestion
Instead of requiring asset creators to create Q3 shaders for alpha blended transparency on FTE, CSQC on init should generate this file for us before the world is loaded to reduce manual UGC effort.

Expected behavior
CSQC automagically iterates through models path to find *$.mdl, creates shader file for item if not already existing in scripts/ with proper blend mode.

[MotoLegacy]

Since this *$.mdl behavior is also very NZ:P specific, a documentation page needs created.
