[WIP] Payum 0.11 upgrade.

In Payum I removed `Request` postfix and renamed some request like `SimpleStatus` -> `GetHumanStatus`. Renamed interactive request to replies so `ResponseInteractveRequest` -> `HttpResponse` reply. Also I added a credit card form, templates support and so on so now PayumBundle can obtain credit card itself. Here I tries to reuse that functionality.  

Some new payments were added, like Strpie.Js, Stripe Checkout, Klarna. They could be easily integrated with 0.11 version of Payum.
This should be in `PayumBundle` not here.
