Requesting room information

Once the player has entered a room, he or she will no doubt want to know who else is there and if there are any games being played.

• To request a list of the players in the current room and what tables the are at, a client may send LIST with type 'player'. The server will respond with a list of PLAYER tags.

• Similarly, to request a list of the game tables in the room, the client should send LIST of type 'table'. The server will respond via a list of TABLE tags.

Rooms are busy places with players entering and leaving, and tables being launched and destroyed. To keep the client from having to continually resend list requests, the server will send periodic updates.
