Updater ignores MySQL Masterserver Port

	$inst->dbmaster = new db();
	if($inst->dbmaster->linkId) $inst->dbmaster->closeConn();
	$inst->dbmaster->setDBData($conf['mysql']["master_host"], $conf['mysql']["master_admin_user"], $conf['mysql']["master_admin_password"]);
	$inst->dbmaster->setDBName($conf['mysql']["master_database"]);

I need this setting. My Master is behind a firewall and i do not want to have the default port opened to the public.
