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
