Add support for mixed currency for invoice payment

This patch extends the payment dialog to allow paying foreign-currency
AP with local currency, or local-currency AP with foreign currency (I
don't know if there's a use-case for the latter, but it would have been
harder to code to NOT support it).

Patch by Jamie Campbell.
