Load mapping and use it for offset, joint mappings, blendshape mappings.
fixed behavior of voxel delete and some cases of voxel add in fast pipeline mode
Fixed incorrect capitalization.
Need to allow multiple blendshape mappings per shape index.

Use Faceshift mapping files (FST) when present for their transform offsets and joint/blendshape mapping.  Fixed crash on meshes with no texture coordinates.

Fixes to delete/add voxel sometimes not rendering
Apply (some) FBX material properties to rendered meshes.
Remove references to ambient, use the requested alpha.
less aggressive debugging of waiting for assignment
Fix for URLs' not being sent: setting the scale calls createMohawk, which
reseeds the random number generator, breaking "shouldDo."

less aggresive assignment debugging
Apply color to ambient material property, too.
Merge pull request #1017 from ey6es/master

Use diffuse color, specular color, and shininess from FBX file.
Handle index-to-direct normals (exported by the Faceshift rig FBX).
Include a mapping for the names generated by the FBX export.
