[PATCH] gateway.d: Add script to set wan vlan/interface

[Fabian Bläse]

Allow setting WAN vlan/interface from gateway config.
A configuration without explicit definition of a WAN interface is
valid at the moment and results in the default vlan (2) being used.

To maintain this behaviour this script sets the gateway config to vlan
2 if no vlan/interface is for WAN specified. This behaviour is transitional and
will be removed in the future.

Fixes: #143
