Retrieve an action from a gio::ActionGroup

• Before:

  Example:

  let actions = gio::SimpleActionGroup::new();
  action!(
      actions,
      "delete",
      move |action, _| {
          // Do something
      },
  );
  let action = actions.lookup_action("delete")
                  .unwrap()
                  .downcast::<gio::SimpleAction>()
                  .unwrap();
  action.set_enabled(false);

• After:

  Example:

  let actions = gio::SimpleActionGroup::new();
  action!(
      actions,
      "delete",
      move |action, _| {
          // Do something
      },
  );
  get_action!(actions, @delete).set_enabled(false);
