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

Connected parents in NiNode::FixLinks and removed NULL ones.

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.

Hopefully fixed the Read/asString bugs.  Niflyze can now read and output strings for all Morrowind files.

Another fix for generated template.

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

Fixed something I broke on last commit + another update to XML in ByteArray: niflyze now reads Oblivion files :-)

Updated license text in remaining files.  Short text in all files except niflib.h, and year updated to 2006.

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.

Got rid of globals for good measure.

Moved things around and updated xml_extract.h so that everything compiles again.  Other than NIF_Blocks.h/cpp which will be removed in the future, of course.

Implemented some of the object hierarchy the new way in nif_objects.h and started updating niflib.cpp.

Removed interfaces and moved documentation to real classes.  NIF_Blocks.cpp and niflib.cpp no longer compile.

Begun work on the new type of Attributes which store pointers to their data rather than the data itself.  Moved some code to new files to fix problems with cross-includes.
Need to decide what to do about TexSource, a struct in the external interface that should have a link in it.
