Use RMStepsController for guiding through setup process

What do you think of this UI for the setup process? The control itself (RMStepsController) is finished and used in version 1.0.0. The Implementation of the single steps is more a prototype (as I did not want to invest too much time in something that will be rejected). If you choose to use this UI, I will make it work ;).
