Fix Math so that it decomposes rotations back to stored rotation and not the inverse.  Fix Scale so that it returns the correct value rather than x+y + (z/3).
Add helper methods for useful flags for importing data in avobject and controller sequence.

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.

Tried to implement functions for NiControllerSequence, but can't until problems in the XML are fixed.

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.
