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.

o Convert pkg-info to pkg-query.
o Thin out unused fields.
o Add flatsize to GUI.
o Way faster.  :D

Switch to GET for now, I think other pages use a mix of POST and GET
in case of 'clear' which doesn't clear the right log for obvious
reasons...

(mvc) remove previous sample from codebase, the helloworld plugin covers more. leave template sample in place, because it provides some additional options of the framework.

(legacy) replace time with microtime in make_config_revision_entry, not needed for the config revision anymore because that method uses it's own timestamp. Revision entries are also used on some other config items, like firewall rules.
