pingback_ping() is not using the check for prior pings

[unbrand]

In xmlrpc.php, pingback_ping() around line 1967, there's a check for prior pings to avoid creating a pingback from the same originating server for the same article. Sounds good, but the check is not used. There's an "if (1==1)" that guarantees the pingback insertion code will be executed. This behavior prevents us from calling pingback_ping() more than once for the same article, which I think we want to do for situations where we want to parse a post body more than once (to pick up additional URIs to ping).

Fixed in the new XMLRPC support.
