Fixed NormalBaker

This script is a fixed version of the default normalbaker.ls script shipped with Lighwtave 3D.
I noticed this script doesn't generate right normals for tripled geometry (and even for non-tripled ones, in some cases ... o_O!)

I also fixed a bug in the script : the Vmap generation was misfunctionning, so the script could not be run more than one time, quite annoying...
