ADD Vertex utility class to simplify conversion from and to interleaved vertices.

Browse Source 
Refactor JoinVerticesProcess to utilize the new utility.
ADD basic operators for aiColor4D, move to dedicated header and implementation file.
ADD some utility functions to SpatialSort.
ADD my existing Catmull-Clark implementation to Assimp for all model formats with support for subdivision surfaces. Slightly WIP, likely to produce errors on non-closed meshes. Currently only implemented in the AC3D loader.
Switch to byteswap intrinsics instead of inline assembly (bswap). Currently MSVC only.
FIX phong shading in assimp_view.
VertexTriangleAdjacency class now also works on arbitrary polygons - UNTESTED, tbd.
