== VRML97 export ==

Patch #10569 from Michalis Kamburelis (sorry for the delay).

This patch adds a popup menu that lets the user choose whether
they want to export selected, whether thay wanted to export
compressed, and whether they want to export the file from
blender's "Z up" coordinates to VRML's "Y up".

I'm not too crazy about the caching to disk of these options
via GetRegistry/SetRegistry, but since this seems to occur
in many of the other export scripts I'll leave it as is.
