* Attribute names of the form thisIsAnAttribute.
* NIF_Blocks.h is included.

XML updates:
* niflibtype(char)=byte
* new basic type "KeyType"

Made it possible to delay telling a Link and CrossRef which block owns them until the point where they store an actual link or cross reference.

Key streaming in NIF_IO.
Added xml_extract.cpp to SConstruct.
!! The extracted files are based on a modified XML, with CrossRef and Link implemented as uint, and char implemented as byte.

TODO: implement CrossRef and Link in niflib.h?

Did some research in the C++ FAQ and found out how to have vectors of objects that have no default constructor:  http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.5  Therefore, LinkGroup and CrossRefGroup were removed and the NifStream functions and << operators were shifted from blk_ref and IBlock to Link and CrossRef directly.  The Python will now just have to worry about inserting the owner into the constructor of all links.

Created NifStream and << operators for blk_ref and IBlock *.  Special code will need to be generated by the Python to handle reading of links.

Created Link, LinkGroup, CrossRef, and CrossRefGroup classes which automate the process of adding and removing links and cross references to a block.  Had to put them in Nif_Blocks to avoid including that file in NIF_IO.

Implemented HeaderString class.
Removed more legacy code from NIF_IO files.

Added several NifStream functions and << operators to the built-in types.
The new xml_extract.cpp file now compiles.
Problem areas that must be fixed in the generation script were marked with !!BUG!!

Changed projects to use Multi-Threaded DLL code generation rather than Single-Threaded.  This should be more compatible with MSVC++ Express Edition.

Moved some temporary defines to NIF_IO.h.

Added optional version parameters to all NifStream functions.  Couldn't figure out why it conflicted with Amorilia's later change so I used my code.
 

Removed split-tree functions from public interface.
Restored WriteFileGroup.

Added SplitKfTree and SplitNifTree functions to the interface. SplitNifTree is implemented for Morrowind only (copied code from old WriteNifTree function), SplitKfTree is not implemented at all. These two functions replace WriteFileGroup.

Updated MergeNifTrees to handle some cross references (skin blocks).  Other blocks with cross references can be added by overloading the ABlock::ReassignCrossRefs function.

MergeActions: read NIF file and all KF files (TODO: merge them as well).

Added documentation to IControllerSequence.

I made some little update to the script to make sure the libs are built in the proper order, and I also commented out the niflyze build string since it resides in another folder
