[TYPO3-commerce] class pi6

[Jeroen Visser]

Hi,
It seems that the pi6 was changed some time ago. I have a old version 
where the function getOrderArticles() uses a result variable 
$res_orderlist and $row_orderlist. The new version uses $res and $row.

The $markerArray['ARTICLE_TOTAL'] was forgotten to change to the new 
variable $row, so it is always zero in the invoice.

Greetings,
Jeroen
