Title: Add IgnoreNormals parameter for STL writer.

This modification adds an IgnoreNormals parameter for STL writer which makes it output STL files with normals set to [0 0 0].

I am using OSG to merge some geometries in a few STL files into one final output. The output is used in a CFD simulation where there is no need for normals. With this patch, the output file, at least in case of an ASCII one, is smaller.
