[nautilus/gtk3-breakage] main: adapt to GtkApplication changes

[Cosimo Cecchi <cosimoc src gnome org>]

commit 20096ffdb13f9c05fd99eff1e327a108b7415fce
Author: Cosimo Cecchi <cosimoc gnome org>
Date:   Wed Oct 27 13:13:48 2010 +0200

    main: adapt to GtkApplication changes
    
    This code should be much easier now that window lifecycle is handled by
    GtkApplication itself.
