Removed unused vars from UpdateTangentSpace().

"Fixed" NiTriBasedGeom::GetSkinInfluencedVertices function so it fails to import meshes with bad overall offset transforms.

Added an exception and some extra checks to NiTriBasedGeomData::UpdateTangentSpace.  Also made minor style changes.
Fixed warning created by changing NiStencilProperty's enabled value to a byte.

1. Update NiStencilProperty based on Shon's changes
2. Rewrote large chunks of WriteFileGroup related routines.
3. Added a WriteNifTree which allows for multiple roots (not exposed publically)
4. Added option to BindSkin to scene instead of skeleton root.
5. Fixed bug in RemoveController
6. Added helpers to NiControllerManager for sequence management
7. Propegated user_version in routines which take a version

2. Fix PCH project settings.
3. Add NifSkope base partitioning algorithm
4. Add ability to use TriStripper instead of NvStripper for tristripdata
5. Sync with XML and equivalent changes.

Updated method names to use 'LOD'.
Added documentation comments.

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 missing NvTriStripper files back into solution.

Updated NiScreenLODNode in Nif.xml to use 'ProportionLevels'.

Fixed the relative include paths and tried to update solution, but havn't got the precompiled header working right.

1. StringOffset now defaults to -1
2. Search in StringPalette now finds exact matches rather than partial matches.
3. Reuse same StringPalette for Controller and all child blocks

2. Convert bspline controller offsets from ushort to uint
3. fix bug in nicontrollersequence with string palette

1. Add BSBound unknown values.
2. Update MotionSystem enum
3. Add LOD Bone Controller handler
4. Fix website references

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

Some simple updates to Niflib documentation.

2. Add some extra helpers around sequence and animation.

Casting functions now check for NULL as of last commit.
