o We could potentially pass files using xml=../../xxx, so just
  hardcode the wizards we know for now.  I don't expect them to
  grow, otherwise we may be able to do a directory expand.

o Move xml files out of the /usr/local/www/wizards into /usr/local/wizard.

o Move the include file to the normal include path /usr/local/etc/inc.

o Allow the menu to always expand to the setup wizard, even though
  we many be triggering the OpenVPN wizard.  This gives a consistent
  feel of navigation, especially since POST requests hide the invoked
  wizard later on anyway.
