FormPreview needs easier extensibility

In addition to #7222 and #8690, I have to override more parts of FormPreview than I'd like to do any additional processing before displaying the preview page. FormPreview should have a hook for additional processing like FormWizard's process_step() method so I don't have to override all of preview_post or put unwanted logic in my template.
