- When suggesting to use Pi-hole, use the VPN server IP instead of the LAN IP to allow

DNS resolution even if the user does not route the local network through the tunnel.

- Format listCONF in a similar way as listOVPN

- Specifically look for a free octet in the last word of clients.txt and not just any word.
  Necessary otherwhise public keys starting with a number will match against an octet.
  Example: if line is 'name 5abcdefgh 4', then looking for ' 5' will match but '5$' will
  not (correctly).

- 'pivpn -c' will show the Connected Clients List for WireGuard too
