Added a Vertical MicroMenu option

The MicroMenu can once again be vertical again, however it does not have a full-blown Rows configuration like the actionbars do, due to some issues with the non-square micromenu buttons.
As a result of that, padding between the buttons is currently not available either.
Its planned to make the MicroMenu use the default ButtonBar template too in the future.
