WebSocket Tab Muter

Tab muter and unmuter based on hotkeys and/or a websocket. Can tie in with a CS:GO Game State Integration service to control Chrome audio based on your in-game status, or can be used independently as a convenient way to mute/unmute individual tabs or to quickly silence all of Chrome.

Also, for no particular reason, incorporates a "close other tabs" feature. Set a hotkey to close everything in the current window except the active tab.
