Merge pull request #1 from justin808/update-latest-justin

Update latest dependencies and address cors issue
Remove switching ports to enable hot-reload

* Add the ajax stubs to the WebpackDevServer
* Remove the 3001 port reference, as well as the cors reference
* Change the name of the webpack.config file to reflect it changes the
  config with the reload. Since that might not be desirable in some
  circumstances, such as using the bundle.js on another server, it makes
  sense to explicitly name the file.
Merge branch 'remove-second-port-and-cors' into es6
