Add Material Texture Offset functionality (just like in Revit's Material Editor)

Add functionality to offset the texture map (just like it does in the Revit Material Editor)
When applying materials to say an embedded Cad import (in my case a surrounding site context mode) you cannot rotate the materials applied to each layer in the imported/linked cad file. Another use case might be where you have a multi-storey building with brickwork walls where each storey is an odd number of brick courses. Revit applies the material from the Base Level of the wall object. Create an 'Odd Level' material with a 75mm offset solves all the issues, and saves you having to go around aligned textures in the model.
