[Feature Request] Start service only option

Hi,

Could xfce4-appfinder include an option (something along the lines of --server, to match the disable option) which would only register the DBus service and persist but NOT show the actual window. This would allow xfce4-appfinder to perform any caching ahead of time (ideally on session start via autostart methods etc.) without actually requiring the user to dismiss the window.

Thanks simplejack
