incorrect default destination on firewall_nat_edit.php
on firewall_nat_edit.php, the destination box has lost its default value. It should be set to the interface address of the interface chosen, and updates automatically when changing the interface. For instance, the default interface on a new entry is WAN, so the default destination is "WAN address". If you switch to interface "WAN2", then destination auto-updates to "WAN2 address".
