ManagedWebSocket - WebSocket wrapper to handle auto reconnecting and event re-binding
/*
* ManagedWebSocket is a thin wrapper around WebSocket that handles automatic reconnecting and re-binding.
* If the server/network drops the connection, it will keep trying to reconnect. However, you may call
* "kill" to permanently disconnect on the client side. The native WebSocket object is available as "ws".
*
* Use "on" to bind to normal WebSocket events (open, message, error, close), and to the following custom events:
* - connecting: Fired when it is attempting to connect or reconnect.
* - drop: Fired when the connection has been dropped by the server or network. (fired before "close")
* - kill: Fired when you call "kill" on the MWS. (fired before "close")
*
