Wizard Component: Automatically add navigation buttons upon adding new step.

It’s a bit of a pain to have to create previous and next nav buttons for each time I add a step in a wizard component. Seems like automatically adding these would be a pretty simple thing to do, and is likely desirable for anyone using a wizard.

Thanks for the good Idea Matt.  We’ll add it to our list. 

Implemented in Banzai! Thanks, Skuid.
