Fixed currency separator and delimiters for es-AR, fi, ro and sv

In es-AR, fi, ro and sv locales the keys *number.currency.format.delimiter* and *number.currency.format.separator* have different values with respective keys in *number.format*.  

According to [wikipedia](http://en.wikipedia.org/wiki/Decimal_mark#Countries_using_Arabic_numerals_with_decimal_comma) all these contries use comma as decimal separator, so existing *number.format* values should be correct and *number.currency.format* values look erroneous.

This pull request fixes *number.currency.format* values to their respective equivalents from *number.format*
