pfSense

These html tags are not required since they are used in head.inc which is included.

Simplify this code a bit, should be the same test in both locations since this should be either/or, and with the other code it can apparently fall into a trap where it shows neither.

Fix field name label.

remove dead link, no equivalent exists, will add info on that page's help

Put rw/ro calls on pkg_edit.php on POST to avoid packages having to do these calls.

fix text

Include the rate output in the privilege for the traffic graph.

Comment out code that seems to not be anymore useful. Remove later on if no complaints in sight.

This reverts commit a26d95383a6146734f67c9db21cd83534052843a.

Make initial changes to allow pfSense to work in a jail.

This mostly avoids starting things that will not work and gets the
initial config. Most of the pfSense functionality will not work
(pf rules, routing, etc) but it can be used for testing.
