Initial changes for skin partition access.  Needs more work around protecting the user from inconsistencies.

2. Put back changes that Shon rolled back to so that exporter compiles again
3. Put in new typesafe helper for creating nodes so we dont have to rely on strings.

Added bounding box related functions to NiAVObject.  Forgot to commit this earlier, so it removes the versions created by Tazpn.
Hopefully fixed the skin calculations.  Results in skin files that always seem to look correct in Morrowind but do not always look correct in NifSkope.

1. Update Niflib based on recent xml changes and cleanup some of the entries added for the 3ds max Exporter.
2. Merged in changes required by 3ds Max Exporter as I try to remove the cloned copy of niflib completely from svn.

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.

Fix Math so that it decomposes rotations back to stored rotation and not the inverse.  Fix Scale so that it returns the correct value rather than x+y + (z/3).
Add helper methods for useful flags for importing data in avobject and controller sequence.

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.

GoToSkeletonBindPosition also works now as well.

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

More functions implemented.  NiNode and NiObjectNET are now good examples of how to deal with pointers.
With implementation of NiNode::GetChildren function, I was able to re-enable the building up of the bind position.

Made all include paths relative so you don't have to set any directories to compile.  Hopefully Amorilia will fix this in the code generation script.
Implemented a few more functions.

Incorporated defines into the h and cpp files I'd already made for NiNode, NiObjectNET, and NiAVObject.

Noticed that I had forgot to include NiObject.cpp in my last commit... unfortunately I've already started splitting off classes into their own files so that's included in this commit as well.
I also noticed that I never implemented the member functions of Ref!  I still haven't, but I was just surprised it's been compiling without complaint.
