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.
we discussed it several times, `~0.11` means we allow 0.12 too but it may contains BC breaks.

BTW 0.11.7 contains a fix for a critical bug https://github.com/Payum/Payum/releases/tag/0.11.7
