Fix my traffic graphs

Unset the correct variables

Make it so that we use the correct fields in the right order

Apply fix from wallabybob on the forum http://forum.pfsense.org/index.php/topic,37079.0.html

Also process v4 gateways on v4 gif tunnels

When editing a gif interface with a gateway we need to call system_routing_configure() for that gif interface.

Test the right variable otherwise we have no hope of getting a v6 gateway

Comment out the interface_gif_configure(). It is causing more issues then it is solving.

Do not use global router advertisements, instead configure per interface.

Fixes #1386. Correct unlooping nested port aliases.
