Update Maldivian Currency to MVR and fix ރ. to be ރ

Update the primary symbol for Maldivian currency to be the new officlal
symbol: "MVR", move the previous symbol "ރ." to an alternate symbol and
remove the "." in "ރ." so that the symbol can be put before or after
the currency amount (If a dot is present, it should always be
in-between ރ and the currency amount)
