19847	"add a ""step_failure"" method on WizardView"	mothsART	nobody	"A little patch for a method i like using : ""step_failure"".

Goal: If you want catch all ""invalid post"" in a wizard forms.
For me, is a good way to log and stats a wizard in production.
Log failure bring me some indications : if a field validation is too complex, if design of form isn't user friendly etc.

This diff is minimmalist and a first suggestion. I'm open too talk about...
(in fact, that will bring API heavier...)
