[TYPO3-commerce] marker for total amount in ###FINISH### part of checkout.tpl

[hartmut]

You guys really force me to think for myself.
Thats not fair.

I found a temporary solution by fearlessly messing with 
class.tx_commerce_pi3.php.

I put the line

$markerArray['###SUM_GROSS###']=$GLOBALS['TSFE']->fe_user->tx_commerce_basket->get_gross_sum();

right after the hook ProcessMarker (line 991).

So maybe I should create an extension using that hook.
But I don't know how to do it, and I'm happy for now.
