Title: Add an ISO currency code accessor to integration notifications.

Cannot be merged until after https://github.com/Shopify/active_utils/pull/30 is merged and the new gem released; the tests won't pass until then.

Just adds an `iso_currency` accessor that we can make use of that will do the ISO currency mapping if needed.
