Opening and closing a modal dialog is not instant. There is a transition animation involved. When the dialog is finished opening, it currently emits the "opened" signal. When it's finished closing, however, it doesn't emit a "closed" signal. This means, there's not a good way to know when the dialog finishes closing. This commit adds the "closed" signal. https://bugzilla.gnome.org/show_bug.cgi?id=694296
