[TYPO3-commerce] ugly hack for payment gateway

[Stephan Viftrup]

Hi Andreas

I have not been looking here the last days so i did not see your 
message. Allthough my way of handling payment is still a ugly hack it 
has become more stable.  I have not used the localconf.php though.

I would much like to see the code you have made so that i can lean from 
your approach if you'll still let me. Perhaps i can be of assistance 
too.
