[Corey Berla <coreyberla src gnome org>]

commit d265277e726e65278fef8ea5e1ec79539c2b9719
Author: Corey Berla <corey berla me>

    app-chooser: Add property single-content-type
    
    If we are acting on a single item or multiple items that all have the
    same mime type, set to true. This will be used for setting the title
    and ability to change file type association.
