#160 allow_only doesn't get checked in dynamically dispatched RestController

[Moritz Schlarb]

In this RootController: http://bpaste.net/show/34255/ you see the UserController that gets dynamically dispatched using _lookup.
The statically mounted controller at /user asks for the manage Permission but the dynamically dispatched one does not.
I verified it happens the same way when you just inherit from RestController.
