Title: Netpay Gateway Support - Mexico

This request adds support for the Netpay (http://www.netpay.com.mx) gateway in Mexico with methods for "purchase", "cancel", and "refund" transactions.

They don't provide public credentials, so please get in touch with me if you'd to test remote requests.

Given the simplicity of the API, the tests are pretty minimal, but hopefully sufficient.
