Fixed double N's in NiTexturingProperty.

More functions implemented.  NiNode and NiObjectNET are now good examples of how to deal with pointers.
With implementation of NiNode::GetChildren function, I was able to re-enable the building up of the bind position.

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.
