Revert "Sage gateway: Deprecate #credit call" This reverts commit 425ffea. I had deprecated the `credit` call 2 years ago thinking at the time that the `credit` was really a refund. In fact it was not. It's a general credit that isn't based on a previous transaction id. I don't see an ability to do a standard `refund` in the Sage docs: http://www.coderxo.com/docs/BankcardHTTPS.pdf For now, this commit removes `refund` since the interface was broken. Closes #1731.
