title: How to make a step optional with django form wizard
body: <p>Django form wizard has a <code>condition_dict</code> which allows skipping of certain steps when conditions are met. What if we don't want to skip a step but make it optional. In other words, the form for that step will still be rendered, but it has both a submit button as well as a skip-this-step button. The submit button will carry out normal form validation, where as the skip button will take users to the next step.</p>
  
  <p>Is this even possible with the form wizard in django 1.4/1.5? If so, please give me some pointers. Thanks.</p>
