Added Head method to IRestClient.  Updated implementation on
ServiceClientBase. Added HEAD verb to several conditional checks in a few
files for 1) enabling use of a query string and 2) to prevent the use of a request body
when submitting HEAD requests (which currently throws a
ProtocolViolationException).
Started on HtmlServiceClient and unit tests to prove session's ReferrerUrl always works.
Finished the unit test (and related core library functionality) to get a failing test without the AuthService session reference fixes and a passing test with the fixes (branch: auth-session-referrer-issue).
Added ability to configure underlying WebRequest.AllowAutoRedirect, as the unit test needed to disable this to get the original response with the Location header.
Cleaned up the unit test to make its intentions clearer.
Simple workaround for auth service using old session instance, however the bug may crop up in other places later.
Cleaned up some sample request-response data I was using for the HtmlClient.
Merge branch 'html-auth-session-referrer-issue' into html-auth-session-referrer-workaround
Added passing unit test (for initial AuthResponse) and failing unit test (for subsequent AuthResponses).
