Generates the toolbar icon images from the FontAwesome font.
First download and extract FontAwesome from http://fontawesome.io/.
Place the FontAwesome.otf file in the tools directory (same directory
as this script).
Generates SVG, PDF in one size (size they are vectors) and PNG, PPM and GIF in
24x24 and 48x48.
