niflib: removed -fpermissive flag from Makefile and fixed 32 bit pointer casts for 64 bit build (reported by guidoj, fixed with hints from Alphax, see issue #2788607)

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.

Finished new MatTexCollection helper class which makes it possible to manipulate material properties and texture objects with the same classes regardless of the intended NIF version.
Realized that only read was implemented for files with version < 3.3.0.13, so implemented write for those old versions as well.

Updated user's guide.

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

More documentation improvements.  Added documentation to NiDynamicEffect-derived objects, removed some obsolete examples, and replaced remaining references to "block" with "object" wherever possible.

Laying the groundwork for Niflib to be able to work on systems with different endian types.  All Read/Write functions now take NifInfo structures which are based by const reference.  These are also passed into the NifStream functions so they will have access to the requested endian type of the NIF as well.  Also added endian detection and swapping functions.

Moved TypeConst function implementation out of header file. Hopefully should fix GCC visibility issue.
Fixed GetIDString virtual function missmatch that was causing the name not to show up when the function was called from a NiObjectRef.
Added Python-specific operator functions to Ref to prevent the wrapper from crashing on Null Refs.

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.

Fixed the array bug by reversing the template arguments and re-doing the declarations in the Python script.

Added support for sub version 4 headers, object storage, and link method.  Some objects like NiNodes already read correctly.

Split some things that were previously part of NIF_IO.h into their own files to make SWIG wrapping work better.

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

Made ShortString an intrinsic type to fix problems with writing them.
Removed extra byte in HeaderString NifStream function.

Moved version constants to a separate file to clear up problems with no longer including NIF_IO.h in niflib.h.

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.

Some other DAoC related fixes to XML.

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

Enabled precompiled headers in MS Visual C++ project.  Also tried some tweaked optimization settings to make it compile faster.

Header and footer code now in the structs. Also small update and fix to NIF_IO HeaderString read/write.

Made niflib more verbose: prints blocks as it reads the NIF file (helps identifying buggy blocks); fixed output of bytes.
