bug in OpenID PHP library prevents setup response

In the JanRain PHP library included with this package, in method _complete_id_res(), if set up is needed, it attempts to call a non-existent function. The following line is in error:

        return SetupNeededResponse($endpoint, $user_setup_url);

It should read:

        return new Auth_OpenID_SetupNeededResponse($endpoint, $user_setup_url);

This is actually fixed, along with many other fixes and improvements, in the latest release of this library from openidenabled.com.
