Changes for One-Page-Checkout

[dreerr]

The function hookdisplayPaymentEU() currently only returns an array for each payment method which includes {'cta_text' => ..., 'logo' => ..., 'action' => ...} but in Version 1.6.1 there are new methods available. So this should be changed to {'cta_text' => ..., 'logo' => ..., 'form' => ...} including the form for each payment on the checkout page, so that a true OPC can be possible.
