pfSense

Remove a duplicated entry slipped in accidentally.
Remove uneeded check on default policy.

Revert dhclient timeout to the default of 60 seconds.

More changes in the attempt to change the logic on filter.inc

Please don't force commit!
Re-apply fix from commit [20700] that got reverted in [20706]

Unbreak filter_rules_generate broked by previous wrong commit which was against HEAD.
Second attempt at reorganizing the logic of pfSense rules.

First attempt at changing the logic of the default rules of pfSense.
This allows for the default rules to be overriden in the GUI.

Forgotten filter.inc support for Floating tab on the Rules section.

Remove both Bill and myself from the (C). Looks like Ermal has
done a rewrite.

Add back Bill to the (C) header, he did far more work on the shaper
previously than I did.

Move $rule portion out of the ng0 check that accidently slipped in. This
combined with my earlier change unbreaks traffic from the firewall itself
and also unbreaks nat redirect traffic.
