FBX add roughness mappings and fixes general some material bugs

Browse Source 
- Fixed bug with FBX so we can import material values from the document for PBR when using StingRay (not Arnold *yet*)
- Adds more explicit errors and makes things simpler to read. Has more sanity checks to be sure things are working correctly
- Lazy Properties fixed items not loading due to capital letter errors in FBX parser
- Added debug tools to the materials so you know explicitly what material mapping is assigned to a texture and where it came from. (enable verbose printing to use this)
- Fix broken material mappings and debug entries properly
- Fix make embedded images properly detected
- Spam less errors for unsupported shading models with materials.

Future plans:
- Arnold materials need converted to PBR model, if possible.
