Livereload?

I'm a fan of livereload so I put it in so I can use it in my projects. I don't intend this to be merged now but to raise the question 1) should LR be out of the box included in oj? 2) should it be available to activate through a config param in ojfile? or 3) should it not be included at all but be like an oj-plugin that one can choose to add?

Convention vs configuration.. :)

What do you think? :)

And I'm not sure if it should go in server.js or maybe elsewhere

(also [node-livereload](https://github.com/napcs/node-livereload) might as well be used insted of [express-livereload](https://github.com/mnmly/express-livereload) which is just a mini wrapper for the former)
