Remove GET method in rnoContent regex, because it can have body content

Per: http://tools.ietf.org/html/draft-ietf-httpbis-p2-semantics-21#section-5.3.1

> A payload within a GET request message has no defined semantics; sending a payload body on a GET request might cause some existing implementations to reject the request.

The above does not preclude or restrict the GET request from having content. Some implementations may reject the request, but this enforcement of noContent (later in line 403) is too restrictive.
