Changed the default linkage to DLL.  You now have to define NIFLIB_STATIC_LINK if you want to use static linking instead of having to define USE_NIFLIB_DLL if you want to use the DLL.
Added a new Debug - DLL configuration.
Static configurations now create either niflib_static.lib or niflib_static_debug.lib, while DLL configurations create niflib_dll.lib and niflib_dll_debug.lib along with niflib.dll and niflib_debug.dll.

Removing old Python-related files.

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.

Split Niflib and Niflib for Python into separate solution files to make explaining how to build them easier.

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

Fixed double N's in NiTexturingProperty.

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

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.
