Custom fields in phpfour's payment library.

I was using Phpfour's paypal library. But while sending custom variables, I am getting empty data for it. I have modified the library and it works as expected. My changes are listed below:

Replace setCustomField function with the below code block:

    public function setCustomField($custom)
        if (!empty($custom)) {
   $str = "";
   foreach($custom as $key=>$value){
     $str .= "$key=$value&";
   $str = substr($str, 0, -1);
   $this->fields->custom = $str;

Also replace the declaration of the function setCustomField in the Abstract class.

abstract public function setCustomField($custom);
Now, you can call the function like below:
$paypal->setCustomField(array('tahsin'=>100, 'hasan' => 200));
You wil get these fields under 'custom' fields in the IPN response.
