Cors Everywhere Test Page

• This page will attempt to load "http://google.com" via xmlHttpRequest with credentials set to true.
• This should always fail by default
• If the script reaches the readyState of "4" with an empty responseText, this presumably means CORS will have blocked the call.
• Enabling the Firefox addon "cors-everywhere" should bypass this restriction.
