Subject: [PATCH] Add script to create iconset (FS#11982).

This script is designed to create an icon strip file from svg images. It is
intended for use with the Tango icons. The icons as configured in the script
should be close to the current Tango icon strip file. Requires inkscape and
ImageMagick.
