Implement redirect to action
The Abstract Controller currently provides a method "redirect" which allows for redirecting to a specified URI. The more common requirement however is to redirect to a certain action / controller / package. Therefore redirect() should take the same (or at least similar) arguments like forward() and an additional method redirectToURI() should be implemented.
- renamed redirect() to redirectToURI() in AbstractController
- implemented redirect() to behave like forward(), fixes #2816
- arguments to MVC requests are arrays now, no longer ArrayObject
