Edge browser support

[azakhark]

We are using web-socket-js in a force Flash mode and it works just fine except for the Edge browser. When running in Edge, error happens in WebSocket.prototype.__createMessageEvent() method because of the Microsoft confirmed bug #7598786. While I don't see Edge in the list of supported browsers, may be there is a chance to work around this to support current release of Edge?

I would accept pull request for the workaround. But Edge browser supports WebSocket (I believe), so it should work if you set WEB_SOCKET_FORCE_FLASH to false, which is usually recommended.
