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

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.

(mvc) add AuthenticationServerField type to model, to select authentication servers (which only exists in the legacy data)

PR: https://redmine.pfsense.org/issues/3670

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...

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

(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.

(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.

Thin out "Status" and "Diagnostics" white at it, although the
overall static page conception isn't consistent at all.  Not
liking this, but something has got to be done.  Won't be the
last commit I think.  :)

(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.

(mvc) add default config revision if none is given, fix for https://github.com/opnsense/core/issues/386
