Added section to docs/form_wizard.txt about extra_context. Thanks, Honza

      that you'll need to run this through the ``safe`` template filter, to

      prevent auto-escaping, because it's raw HTML.

It will also be passed any objects in ``extra_context``, which is a dictionary

you can specify that contains extra values to add to the context. You can

specify it in two ways:

    * Set the ``extra_context`` attribute on your ``FormWizard`` subclass to a

      dictionary.

    * Pass ``extra_context`` as extra parameters in the URLconf.

Here's a full example template::

    {% extends "base.html" %}
