Implemented functions for NiTriShapeData and made old NiTriBasedGeomData...

Implemented functions for NiTriShapeData and made old NiTriBasedGeomData functions work with the new system and removed the necessity to re-size the vertex count before setting new vertices.  NiTriBasedGeomData::SetVertices now simply clears out all other data.
Radius and Center functions should be removed from DocSys.
