Default is to serve the wrong content type.

[michael-lloyd-morris]

Given:

func newServer(rootDir string) *http.Server {
	fs := http.FileServer(http.Dir(rootDir))
	mux := http.NewServeMux()

	mux.Handle("/", fs)
	srv := &http.Server{
		Addr:    httpPort,
		Handler: mux,
	}

	return srv
}

That should set up a basic usable webserver for static files like, say, the ones generated by the Hugo project right? Wrong.

Js files - served as text/plain. CSS files - text/plain. HTML file, you guessed it, text/plain. While you can configure a browser to ignore this, it throws a wrench into testing.

This is a bug because it renders this library call unusable as far as I can tell.

Every similar library in ever other language I've used infers the content type from the extension by default.
