niflib:  Add InertiaMatrix as first class niflib type. Add qhull to niflib. Add UpdateMassCenterInertia to bhkRigidBody and supporing bhkShape objects.

niflib: Update to match nif.xml.  Replace Float4 with Vector4.  Use Vector4 in bhk objects.  Introduce default values for array types.

Updated user's guide.

Updated Niflib to the latest XML which adds support for bhkMeshShape, NiMultiTextureProperty, NiRawImageData, and NiSequence.

Re-exposed IDENTITY constants and marked then NIFLIB_API.  Now you must use MatrixXX::IDENTITY instead of MatrixXX::Identity() again.

Made Header and Footer functions NIFLIB_HIDDEN.
Fixed comment on NIF version 3.1
A manual change by Amorilia to the generated Header.cpp and Footer.cpp files was overwritten.  This needs to be fixed in the Python script.

To allow for DLL mode, the IDENTITY constants in the Matrix classes were made private and are now accessible through the Identity() function of each matrix class.  This may affect the 3ds Max plug-in as well.

Replaced GetSkinInfluencedVertices function with GetSkinDeformation function which takes in references to two vectors and fills them with the skin deformed vertices and normals
Added constructor to Matrix44 to convert from Matrix33.

Replaced _WRITE, _READ, _STRING, AND _FIXLINKS defines with the corresponding internal function call.
Replaced STANDARD_INTERNAL_FUNCTIONS with the internal function signatures.
Made my Doxygen config file use relative paths and added it to SVN so everyone can generate the same documentation for themselves.
Removed includes WZ added to ComplexShape.  These were not missing, they are up to the user to include if they wish.

Removed unused vars from UpdateTangentSpace().

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.

Initialized TexCoord values to 0.0f.
Added Visibility flag functions to NiAVObject.cpp
Fixed NiTexturingProperty::SetTexture to set the internal hasXTexture variables correctly.

Tried to implement MergeNifTrees for KF files with a NiControllerSequence root.  Untested.

Finished Skin API except for NiSkinPartition.  Part of this was making NiSkinData read-only with a new interface.
Fixed a bug in the SubtractRef function.

Commented out functions written by Amorilia that I need to figure out how to fix.

Major update to python generation scripts and others.  Currently just namepace and mutable size members with appropriate generated code.

Implemented a missing Matrix44 function.
Updated ByteArray files to current generated versions.

GoToSkeletonBindPosition also works now as well.

Implemented Color3 object.
Adjusted project settings to make the Maya importer link faster.

Made DLL creation optional and added a "Release - DLL" configuration.  The Release configuration creates a static library.

Updated license text in remaining files.  Short text in all files except niflib.h, and year updated to 2006.

Moved things around and updated xml_extract.h so that everything compiles again.  Other than NIF_Blocks.h/cpp which will be removed in the future, of course.

Removed BoneToMatrix44 helper functions. (They will be implemented in Python in the Blender exporter.)

Added a function to calculate an X-aligned bone matrix from the bone vector and the bone roll, which is convenient to have for the Blender exporter.
