[ENet-discuss] Ping servers

[Lee Salzman]

Using a full ENet connection for that is overkill. Use the enet
socket functions to set up a raw UDP socket, and simply have
each client send a packet with its local time to the server. The
server just sends a UDP packet back with that time to wherever
it came from.
