It's time to enable the verification.  the packagaes are being
signed since the original commit went in and all tests have
shown that this works as expected.  Staying safe, you know...

prepare for new mvc framework, we use two different document roots in our new setup to separate legacy and new code.

o Do not keep the login error in the session for
  reloading the page without resubmit will yield
  a spurious login error.

o Pad and reword the message and paint it black,
  eh, red.

Javascript went away, caused error, yadda, yadda...

Next step in integrating our new MVC framework, the mainmenu in the left panel uses the same logic now for both legacy as new content.

- add feature, hide empty items
- configuration in /usr/local/opnsense/mvc/app/models/OPNsense/Base/Menu/Menu.xml

Proxy, ftp added directory tracking and http internal conversion as default for content blocking, work with standard acl list
