Game events required by client

• Player joined game
• Player left game
• Player idle for too long (i.e. kicked out => game cancelled)
• Player ready
• Game state changes

Cross-cutting concerns

• Player leaving game session: Closing the browser window mid-game after joining a game.
• Player rejoining game session: Reopening the browser window for a game that player joined but left previously.
• Player idle in game session: Every game session opens 1 socket connection per player; to avoid players abusing these connections, connections need to be released if player is idle for too long.
