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

1. Add BSBound unknown values.
2. Update MotionSystem enum
3. Add LOD Bone Controller handler
4. Fix website references

1. Update Niflib based on recent xml changes and cleanup some of the entries added for the 3ds max Exporter.
2. Merged in changes required by 3ds Max Exporter as I try to remove the cloned copy of niflib completely from svn.

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.

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.
