Remove "Allow IPv6" option from Firewall/NAT tab, it's already on the Networking tab with other IPv6 options.
Block all IPv6 traffic by default, since IPv6 isn't supported, there isn't any way to add such rules in the GUI, and nearly all users won't want IPv6 to traverse their firewall at this point. Add "Allow IPv6" checkbox to disable this behavior.
Remove ftp-proxy/pftpx/ftpsesame references we handle all of this in kernel now.(yay!)
Fix typo
Correct config path so filter rules are generated again for staticroutes.
Remove ocurrences of m0n0 for shaper type in the code.
Split random-id and no-df option for scrubbing.
Break before information text to match other pages
Move the 'advanced users only' notice into the tab body so the tab headersare not displaced by this message.
Cleanup the tab format of the system advanced pages. The edges were squareinstead of rounded like most pfSense pages.
Break out the advanced system options page into tabs group by categories.Fold the sysctl tunables page into a tab under the advanced options page.This reduces the top level menu options by one. There should be nofunctional changes.
