Now 'GoTo' and 'FixIt' commands don't need to start with those prefixes. For 'FixIt' we can detect the response type by looking for the 'fixits' entry in the response. For 'GoTo' this is a touch harder, as there is no completely obvious way to tell. However it is unique in this respect, so we can simply fall back to it. Completers returning other types of response are not supported by this client.
