Websocket security

Ok, I think the issue is that by default the WebSocket example just uses the net library to initialise a connection, not tls: https://github.com/espruino/EspruinoDocs/blob/master/modules/ws.js#L94

So ideally changing the library to do this:

WebSocket.prototype.initializeConnection = function () {
  require("tls").connect({
    host: this.host,
    port: this.port
  }, this.onConnect.bind(this));
};

would probably work. Unfortunately the way it's done (not actually exporting WebSocket itself) means that you can't actually modify just that function when loading in the library - you'd have to copy the module, change it, and load it in yourself.
