Backward incompatible changes:
Update worldpay host URLs. WorldPay recently communicated that their host URLs are changing. "If you were previously using RBS WorldPay links such as https://secure.wp3.rbsworldpay.com/wcc/purchase you will need to ensure that these are replaced with https://secure.worldpay.com/wcc/purchase to ensure that your site continues to be able to send payments through WorldPay's systems." The documentation currently lists the new URLs http://www.worldpay.com/support/kb/bg/htmlredirect/rhtml.html This change updates the URLs as required.
