improved this script

* use mesh.transform instead of a python matrix multiplication function.
* use the image filename rather then ID name for the URL
* use the scenes world rather then the first world for getting world data.
* mesh.verts.index(face.vert[i]) is extreamly slow!, use face.vert[i].index instead. also got rid of a face loop in a face loop that didnt do anything.

Still need to move this script to Mesh from NMesh
