	* app/widgets/gimpdialogfactory.[ch]: Added boolean parameter to
	gimp_dialog_factories_toggle to make it possible to ensure a visible
	toolbox.

	* app/actions/dialogs-commands.c: Use the new parameter to ensure
	toolbox visibility after the last image window closes.

	* app/display/gimpdisplayshell-callbacks.c: Changed accordingly.

	Fixes bug #137057 (the discussion is in bug #152285)
