Title: Add eWay Rapid 3.0 gateway

This adds support for eWay's Rapid 3.0 API to ActiveMerchant. Rapid 3.0 is a transparent redirect API by design, so this gateway provides both:

* A standard ActiveMerchant `#purchase` API for PCI compliant environments.
* A non-standard `#setup_purchase` + `#status` API that eases using the transparent redirect for merchants that want to avoid PCI compliance concerns.

Includes documentation, unit tests and remote tests.
