Sending item details

[tcz]

As per the CyberSource API docs there are several additional fields that items accept. I made changes to send these along too.

An example:

$cybersourceApi->add_item(
    '55.00', // unit price
    1, // quantity
    array(
        'productCode'   => 'electronic_good',
        'productName'   => '50 credits',
        'productSKU'    => '111',
    )
);
