Updated Niflib to the latest XML.  This significantly improves the hierarchy and adds support for BSWindModifier.

Updated to the latest XML, which adds support for NiBinaryVoxelExtraData, NiBinaryVoxelData, NiPSysCollider, NiBone, NiPSysSphericalCollider, and NiTriShapeSkinController.
Removed erroneous bhkMeshShape object.
Added support in the version parsing functions for versions such as "3.03" which were being parsed as "3.3.0.0" before.  These will now be parsed as "3.0.3.0."
All Bridge Commander demo NIF files other than those that contain voxel 3D textures can now be read.
All DAoC demo NIF files except those of version 2.3 and those that do not appear to store NIF data can now be read.

Updated user's guide.

Added functions to NiImage and NiTextureProperty to allow texture name to be manipulated in <= 3.1 files.
Updated ComplexShape to take the above objects into account when deciding whether to include UV coordinates.

Fixed several bugs that were preventing support for old 3.1 and below files from working.  Many of these can now be loaded.
Added version 3.1 to list of "supported" versions.

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

Objects now have a Create methods and register themselves in the global object map with pre-main initialization, making obj_factories.cpp obsolete.

Re-exposed TYPE constants and marked them NIFLIB_API, making the TypeConst function obsolete.  You now must use NiObject::TYPE instead of NiObject::TypeConst() again.

Added ClearHardareSkinInfo function to NiTriBasedGeom so that SetSkinPartition functions could be made NIFLIB_HIDDEN.

Removed access to unknown data in NiPSysEmitterCtlrData.

Some function and enum name changes in NiAlphaProperty and NiStencilProperty to be more consistent with OpenGL and the rest of Niflib.
Removed access to unknown parameters in NiSourceTexture and merged file name access functions.

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

Removed redundant Get/SetHidden functions from NiAVObject, use Get/SetVisibility instead.
Renamed Get/SetCollision to Get/SetCollisionMode in NiAVObject.

Moved ListAncestors and FindCommonAncestor helper functions from inside of NiGeometry to public interface.

* spelling fix in NiAVObject (SetCollsion -> SetCollision) - affects public interface, however I did not find SetCollsion in any of the plugins so nothing should be broken

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.

* removed NIFLIB_API from TYPE in bhkEntity.h

* NiSkinInstance hiding fix
* looks like everything works; now DEBUG=False in scons to reduce library size

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.

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.

Fixed Niflib DLL compile.  All public functions should now be marked with either NIFLIB_API or NIFLIB_HIDDEN.  May have missed a few here or there but they should be noticed eventually.

Realized that Niflib was not compiling in DLL mode, so started working on fixing that.  All NiObject classes need to have NIFLIB_API and NIFLIB_HIDDEN put on each public function, rather than marking the whole class.  Still a lot left to change, but niflib.cpp and ComplexShape.cpp both compile without errors in DLL mode now.

  header and NiNode for now)

* created a common swig interface "common.i" to be used by all modules

* smart pointers now use the __call__() method, again this reduces the
  wrapper size

* removed __str__() from the niflib API as it does not belong there,
  instead renamed asString() to __str__() in the common.i interface

* version constants now also belong to the Niflib namespace

* SWIGFLAGS are now defined through scons environment, so we only need
  to set them once

* extra settings "-fcompact" and "-fvirtual" to SWIGFLAGS to reduce
  wrapper size

* enabled niflib as a shared library under non-win32 platforms
  (still need to find a solution for win32) under scons

* removed "pyniflib.h" and instead added CreateNiNode wrapper to ninode.i

* renamed "pyniflib.i" to "pyniflib.i_old" in case I forgot to port
  something to the new modularized system; to be removed in future

Changed some functions to use pointers instead of Ref templates.
Updated to latest XML description.
