Rw/registration take 2

@georgebrock I think I much prefer this approach with regard to the wizard. 

I've designated a controller for each Registration step, and just name spaced each step so the controllers and views live in a /registrations folder. This way I'm not forcing everything through one controller action and being overly clever.

My biggest concern was naming the controllers and organizing the files but the name spacing appears to take care of this nicely and makes sense IMO. 

What do you think?
