* Implement leaderboard (shows top five players).
* Make color be decided on server side (make sure we reuse the correct colors)
* Better cache frames during 'requestFrames' mechanism
* Make sure we die when we disconnect.
* Make sure that new client doesn't consider all players as new clients (remove newPlayerFrames, and use Player.waitLag instead)
* Have default player name be empty (or "Unnamed")
* Fix refresh issue when new player joins game.
