* bug fix in Header block (array<3,LineString> crashes gcc when destructed)

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.

number of objects are supported so far, to reduce the size of the
wrapper. Details:

* set property eolstyle:native on .cpp and .h files for better windows + linux 
  support

* added small cpp file for quick nif read and write test (for
  debug purposes)

* fixed memory leak due to array of non-fixed sized objects:
  Header.copyright (caused segfaults under GCC)

* disabled pragma warning on NvTriStripObjects.cpp

* fixed undefined behaviour of map[...] = ... map.size() ... in
  niflib.cpp (caused segfaults under GCC)

* cleaned up SConstruct file
  - if DEBUG is false, TUNE is assumed
  - added TEST option

* workaround in pyniflib.h for ReadNifTree (need to find better solution!)

* swig wrapper interface: NiNode, NiAVObject, and NiObjectNET are
  fully supported (nothing else, for now)

* now using unittest for python test script(s)

Properly capitalized include file names in niflib.cpp.

Fixed strange bug.  All files now load again, and Niflib is now destroying objects properly and reporting the right number of Objects from NiObject::NumObjectsInMemory.

Several fixes to XML and Niflib to enable all my files from Freedom Force (except with NiClodData), Oblivion, CivIV, Morrowind, Zoo Tycoon 2, and DAoC to load in Niflib and NifSkope.
Includes the two strange Oblivion files with version 3.3.0.13 and version 10.0.1.2.

Added support for sub version 4 headers, object storage, and link method.  Some objects like NiNodes already read correctly.

Changed WriteNifTree, and WriteFileGroup functions to take NifInfo structures instead of version and user_version arguments.
Changed ReadNifList and ReadNifTree to optionally fill a passed in NifInfo structure with information from the header of the NIF file they read.
Fixed some tabs that were done with spaces instead of actual tab characters.
Updated from XML.

Fixed the relative include paths and tried to update solution, but havn't got the precompiled header working right.

Made ShortString an intrinsic type to fix problems with writing them.
Removed extra byte in HeaderString NifStream function.

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.

Removed some cout statements I had left behind.
Fixed problem with NiSkinInstance attaching itself to the skeleton root on load.
Increased debug limit on strings to 4000 to allow a particular Oblivion file to load.

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.

Header and footer code now in the structs. Also small update and fix to NIF_IO HeaderString read/write.

Moved all generated files to gen sub directory.
Renamed some generated files.
