A game discovery server accepting registrations via udp datagrams. Simple. Easy. No hassles.
This lobby service has been written for the game Zank. It's about finding documents to retire politicians. The name President was chosen because it's the most high level politician.

| GAMES | list;gametype | List all games of type 'gametype' |
The server will always respond with ERR or with ACK to confirm the state. If the message 'GAMES list' is sent, the server will reply with a list of games is the format: ACK;gamelist\n address;port;name\n
Games will be autoremoved after 10 minutes of inactivity. Keep your server PINGing.
Gameid's are based by hashing the src-ip and announce port using the first algorithm that getHashes returns. Nothing fancy.
Game type (second parameter of REGISTER and GAMES) is usually zank. But if you want to use the protocol for your own game give it another id.
