Fix Typo, although the host might indeed be loca. We'll just keep it local instead.

Allow for Null routes

Always add a link-local of fe80::1:1 when the interface is set to track6. This allows webui access over IPv6 to a easy address.
Make a shortcut in the get_failover_interface() function to get_real_interface() if we find the interface in $config.

Teach rc.initial.ping at least a little bit about ipv6.

Unbreak php errors on login form

Include the gateway functions in rc.banner to prevent throwing a error

Add Gateway Group support to the IPsec interface drop down.
Edit of gateway group correctly reflects the new IP Address.
We need to make a blacklist for interface names in the gateway group edit page.

Allow for failover DynDNS hostnames.
replace get_real_interface() calls with get_failover_interface. If it isn't a group we call get_real_interface() anyhow.
We can't put the logic inside get_real_interface() as this would create a recursion

The gateway groups array now knows about vips to be tied into that gateway group so we can tie the groups into services.
