Started with adding handler for authentication challenges
Integrated ChallengeHandler that is used on authentication requests.

First implementation that integrates the ChallengeHandler into HTTPRiot (main code was taken from the AdvancedURLConnections example provided by Apple). This code is still untested but compiles.
I'm currently not quite happy that we need to add a view controller as root for modal view controllers. But I don't see a better way now.
Registering of authentication handlers (see ChallengeHandler method registerAllHandlers) needs improvements. It is still hard wired.
