Added code to ensure that bones have their flag set properly, even if they are not so in the original NIF file.

Finished Skin API except for NiSkinPartition.  Part of this was making NiSkinData read-only with a new interface.
Fixed a bug in the SubtractRef 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.
