[Tracker] Possible Tracker applet /preferences enhancements

["Jaap A. Haitsma" <jaap haitsma org>]

Hi,

Currently tracker has two preference dialogs: one for the indexer and
one for the applet. Furthermore it's also not that easy to add the
track-applet to the panel (you need to start it from the command line)

My suggestion would be to merge the preferences of the applet into the
one of the indexer. Furthermore there could also be an option in the
preferences to add the applet to the panel
