websocket support

[Joachim Schiele]

when using gocraft/web one has to server websockets on a different port than the legacy http service.

i've added example code below, as one can see:

• ws server is on port 12345
• gocraft's router is hosted on port 8080

i want both to listen on 8080, how to do that?

main.go

func main() {
  server := ws.NewServer("/websocket")
  go server.Listen()
  go http.ListenAndServe("localhost:12345", nil)   // Start the WS server!

  go inotifyWatchDir("output"); // FIXME hardcoded path

  router := web.New(Context{}).                   // Create your router
        Middleware(web.LoggerMiddleware).           // Use some included middleware
        Middleware(web.ShowErrorsMiddleware).       // ...
        //Middleware(web.StaticMiddleware("../output")).
        Middleware(web.StaticMiddleware("output")). // FIXME hardcoded path
        Middleware((*Context).SetHelloCount).       // Your own middleware!
        Get("/", (*Context).SayHello)               // Add a route
  http.ListenAndServe("localhost:8080", router)   // Start the server!
}

example websocket implementation i'm using:

gorilla websockets

as pointed out in #24 i would also consider using gorilla websockets but i do not have a clue how to use the Hijacker interface.

@phea ideas?

@qknight - here's an example that should get you started:

This is https://github.com/golang-samples/websocket/tree/master/websocket-chat/src modified for gocraft web.
