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.

Commented out non-generated files from pch.h so that everything is not rebuilt any time a header changes.
Implemented functions for various key containing objects.

Enabled precompiled headers in MS Visual C++ project.  Also tried some tweaked optimization settings to make it compile faster.
