Add WireGuard, DNS and more to the web UI and router-setup

Browse Source 
Web UI: a WireGuard page (tunnels, peers, keys made on the router, client
configs with a QR code, import of wg-quick configs, live status), a DNS page
(records, wildcards, forward zones), interface dropdowns with VLAN devices,
IPv6 options and a local domain. router-setup asks about VLANs, IPv6 and
the domain. The router publishes its own name in DNS and hands the local
domain to DHCP clients; wg and jq are on the router. Includes a script
that takes over antigua's tunnels.
