Title: fixed concatenation-priority-bug

I didn't tried it with the original-code but in my little test-script
(below) with the IPN class, I got this error:

Notice: Undefined property: IpnOrderItems::$setOptionName in
/htdocs/test/index.php on line 739
Fatal error: Function name must be a string in /htdocs/test/index.php
on line 739

this should be line 326 in your class.

$i = 1;
$t = new IpnOrderItems();
echo $t->setOptionName.$i('test');
