* This function parses the given response from a clientLogin request

*
* @param gc The PurpleConnection. If the response data does
* not indicate then purple_connection_error_reason()
* will be called to close this connection.
* @param response The response data from the clientLogin request.
* @param response_len The length of the above response, or -1 if
* @response is NUL terminated.
* @param token If parsing was successful then this will be set to
* a newly allocated string containing the token. The
* caller should g_free this string when it is finished
* with it. On failure this value will be untouched.
* @param secret If parsing was successful then this will be set to
* a newly allocated string containing the secret. The
* caller should g_free this string when it is finished
* with it. On failure this value will be untouched.
* @param hosttime If parsing was successful then this will be set to
* the time on the OpenAuth Server in seconds since the
* Unix epoch. On failure this value will be untouched.
*
* @return TRUE if the request was successful and we were able to
* extract all info we need. Otherwise FALSE.
