[TYPO3-commerce] ugly hack for payment gateway

[Andreas Stauder]

Hi Stephan,

just a question: how have you integrated the new payment type? If I 
write it in typo3conf/localconf.php it will be overwritten by 
ext_localconf.php . How have you done it?

I'am working on a similar thing: A payment gateway in Switzerland. But I 
have done the first step with a hook. I can send you the code when 
finished...

Thanks for your help
Andreas
