[Twisted-Python] HTTP Basic Auth using cred, an example

[Itamar Shtull-Trauring]

I've put up some code showing how to use HTTP Basic authentication
together with cred to guard a resource at
http://www.twistedmatrix.com/users/roundup.twistd/twisted/issue393

You need to implement a realm that returns resources, and then wrap it
in a portal with an appropriate username/password credential checker.
