commit ba602c17d4eddb4b415ab3ff81295fc2365e45ac
Author: Jasper St. Pierre <jstpierre mecheye net>
Date: Sat Nov 2 20:13:42 2013 -0400
appDisplay: Use the desktop file index for app searching
Rather than scanning all apps for searching, use Ryan's new desktop
file index and the glib support APIs for app searching instead of our
own system.
