Extend support for all currencies listed in the SIPS documentation,
including the decimal numbers per currency. Move this hardcoded data
is a less annoying place.
Remove unnecessary code (e.g. checking if there is more than one payment
with the same reference, which can't happen due to a SQL unique
constraint from the payment module).
Code clarity while I'm at it.
