Add custom formatting for languages and support for cents

Currently default BigDecimalToBankingMoneyConverter has FORMAT = "%s %s %02d/100" and it's used by many languages.
Also we have HindiBigDecimalToBankingMoneyConverter that is using a little different format - "%s %s%s %s".

What could be cool - is ability to use custom formatting without implementing custom BigDecimalToStringConverter and also per-language cent symbol support. Now by default it's printing "one hundred EUR 42/100", and it could be nice to be able to print something like "one hundred EUR forty two cents". For now we can only customize currency - EUR, but not cents.
Also good example example: zł. and gr.
