Unhandled HttpAntiForgeryException when submitting Register form when JavaScript is disabled in the browser.

[claycompton]

To repro:

1. Disable JavaScript in your browser of choice. In IE, add qa.nugettest.org to the Restricted Sites zone and set Active Scripting to disable for that zone.
2. Navigate to https://qa.nugettest.org/account/Register.
3. Without typing anything in any of the fields, click 'Submit'.

Result: You'll get the White Screen of Death. A review of error logs shows that the underlying error is:

System.Web.Mvc.HttpAntiForgeryException: 
The required anti-forgery cookie "__RequestVerificationToken" is not present.

The full stack trace is available at https://qa.nugettest.org/Admin/Errors.axd/detail?id=107.

Expected: No such error. We should, as far as possible, support clients that don't have JavaScript enabled.

See #1315 for another case where this occurs and should be fixed.

The problem isn't JavaScript, it's Cookies. When IE requests a site in Restricted Sites, it refuses to send any of the cookies. I'll do a quick pass to see if I can report the error slightly better but if not I'm just going to "Won't Fix" this as our site requires cookies for many reasons.
