Would it be useful to have @BeforeStep and @AfterStep hooks?

[janschaefer]

Currently it is not easily possible to do an action before every step or after every step. Would you think that it make sense to introduce such life-cycle hooks? One example use case would be to take a screenshot after every step, for example.
As an alternative we could also introduce a listener interface that is attached to the stage. Something like:

@StepListener( MyStepListener.class )
public class MyStage {
} 

public class MyStepListener implements StepListener {
     public void before(CurrentStep currentStep) { 
         ....
     }
     public void after(CurrentStep currentStep) {
         ....
     }
}

As a workaround for the missing @AfterStep I started to override the self() method assuming that I call it at the end of each step.
