[TASK] Nodejs server for dev use instead of apache

I have the entire dev environment running on my windows machine now, using this nodejs server instead of apache.

As you can see, I haven't made any changes to the README yet. I don't mind adding some documentation to the readme, describing how to set this up and use it, but there are a couple more things I would like to do before putting it in the readme. E.g.:
- Setting up some sort of automatic creation/download of a ripple.txt file which is placed in build/bundle/web
- Remove the need for the user to manually generate an SSL key/cert pair
- Add a grunt task to start the nodejs dev server
