    nautilus-view: disable open with app for multiple selection
    
    In 3.15.90, selecting two (or more) files and right-click > “Open with another
    application” silently fails to open the application-chooser dialog. So what we
    want here is hide that menu item when the selection is bigger than 1 item.
