Glowmarkt binding: Authentication failure not handled gracefully due to Jetty AuthenticationProtocolHandler

[rtuck99]

If the supplied password is wrong, the binding reports the stack trace below, because Jetty Http Client expects WWW-Authenticate header on 401 and then throws ExecutionException, rather than just returning the 401 response code. We should configure the client to ignore this, so that we can get a more sensible error message.
