Create a new action

• Before:

  Example:

  let widget = get_widget!(builder, gtk::Window, widget);
  let actions = gio::SimpleActionGroup::new();
  widget.insert_action_group("export", Some(&actions));
  
  let action = gio::SimpleAction::new("do", None);
  action.connect_activate(move |action, _| {
      // Do something
  });
  actions.add_action(&action);

• After:

  Example:

  let widget = get_widget!(builder, gtk::Window, widget);
  let actions = gio::SimpleActionGroup::new();
  widget.insert_action_group("export", Some(&actions));
  action!(
      actions,
      "do",
      move |action, _| {
          // Do something
      },
  );
