Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
- converting nurbs to mesh was casting the material to unsigned char.
- subsurf was casting to char, then int -> short in a loop.
- have material functions take & return shorts.

This patch adds an option to export only the selection.

The export was not really wrong, but Maya expects their profile to be present inside <geometry>. Added this for mesh with ME_TWOSIDED flag set.
Ideally this will change in the future to be controllable through options to the exporter (like current Google Earth and 3DS Max extensions for <double_sided>).
