UI: New browser title management

[Dorfieeee]

• The icon blinks from old to new 3 times before settling to indicate change.
• The title updates in background(not active tab).

{icon} {serverName} ({numCurrentPlayers}) | {timeRemaining} | {mapName}

const icons = {
idle: "⚫",
empty: "🟡",
loading: "🟠",
error: "🔴",
normal: "🟢",
ending: "🏁",
};

const numberOfBlinks = 3;
const blinkInterval = 500;
