Title: Make a non_fractional_currency? accessor public

@angelini please review

Makes `non_fractional_currency?` public and on the `Gateway` object.

Stripe has it's own list of non_fractional_currencies. I could DRY it up but it would add more currencies to the list than what Stripe has already and well, I don't want to mess with it.
