Campbell Barton fcc377e204 [#13635] DirectX8Exporter with vertex colors 
patch from Masaru Nemoto (mnemoto) 

Made some modifications to the patch, use reduce() to get total face verts and some speedup for face vcol looping, also don't write vcol alpha since its used by brushes internally and has no useful meaning.
