Subject: [PATCH] Capitalize currency and country codes automatically

Payment context already force-capitalizes the currency code before attempting to create a PKPaymentAuthorizationViewController but this other helper method does not. iOS now returns nil for PKPaymentAuthorizationViewController if the request you create it with has a lowercase currency code so capitalize it automatically for people.
