Future-dated transactions

More flexibility for businesses that post-date invoices.

Zamp now accepts transactions dated in the future, such as post-dated invoices.

Future-dated transactions are calculated with the tax rules in effect on the day they are created. If rules change before the transaction date, the tax could be out of date, so this works best when used with that in mind.
