(captive portal) work in progress rewrite captive portal feature using new framework and standards... lots of things to do here, but we've started.

(cherry picked from commit 44edcd0c)

It looks like the new components are not yet setting a different
language internally.  Time to fix that, huh...

Not sure why "Static" should be special.  Skipping over LAN setup
is ok, skipping over admin password change is NOT.

JS regex validation should die, but so should this wizard so
just touch up on the subject of IP validation, improving:

o Allow leading zeros
o Fail on x.x.x.0

(cherry picked from commit 904029d1)

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.

(cherry picked from commit f5eb5ea8)

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...

(ui) add tokenizer support on edit in UIBootgrid, eventually we should probably break up this wrapper a bit more. it works, but feels a bit too complicated.
