Really put the skin calculations back the way they were this time.  Helps, but the hands of better bodies meshes still end up in the wrong place.
Added transform parameter to ComplexShape::Split because changing the transforms after the fact ruins the skin binds.

Added a max_bones_per_partition parameter to ComplexShape::Split and NiTriBasedGeom::GenHardwareSkinInfo in anticipation of Tazpn adding that capability.

Added != operator to Matrix44.
Added IsSplitMeshProxy function to NiNode.

Created a new ComplexShape class which can currently be used to automatically split the sort of complicated mesh that contains per-point-per-face attributes into NiTriShape classes.  Should support skinning as well, but has not been tested.
Added TexCoord == operator.
Changed type of Triangle members to unsigned short.
Color4 now defaults to all zeros.
NiAVObject::AddProperty now takes a const argument.
Fixed exception in NiTexturingProperty to throw a runtime_error instead of a string.
NiTriBasedGeom::BindSkin should now automatically finds the skeleton root by itself.  The skeleton_root argument has been removed.
