Added an *RLV On* button to the main menu for the doll or controllers
the button is only visible when the RLV check has failed if RLV is ok
or if the RLV status is still being checked the option will not show.

As such a more clear indication that the RLV check is as yet unfinished
has been added to the Main Menu, now the RLV status text will read that
RLV is still being checked and as such some features will be unavailable
as opposed to simply stating no RLV.
