* Dont ever copy autostart files into ~/.config/autostart
	  if the corresponding system autostart file has an
	  AutostartCondition stanza
	* This should prevent autostarting nautilus twice when using
	  Nautilus >= 3.1.x
	* Improve logic to support user installed desktop files
	* Why isnt this complex autostart handling not in GLib
	  or GApplication or something...
