I wonder if we really need it. It's true that the number of singleton
services we have in Xfce is increasing (thunar, session manager, power
manager service, xfrun4 in 4.8, xfrun4/xfce4-appfinder in 4.10, ...). 

At least Thunar and xfce4-power-manager we already have this
implemented their own ways and I don't expect those implementations to
change much. So maybe we can avoid adding a unique-app feature and
switch to GApplication/GtkApplication once we switch to GTK+ 3.
