Added connect-livereload snippet

This removes the need for installing LiveReload as a plug-in.

You could optionally pass in — and check for — a LIVERELOAD_PORT env in much the same way as PORT.

Nice! This is a really useful change.

I actually use it like:

var livereloadPort = process.env.LIVERELOAD_PORT;

if (livereloadPort) {
  app.use(require('connect-livereload')({ port: livereloadPort }));
}

And then in my Gruntfile.js (I'm using grunt-nodemon)

nodemon: {
  options: {
    env: {
      PORT: APP_PORT,
      LIVERELOAD_PORT: LIVERELOAD_PORT
    }
  }
}

I would have added something like that to this PR, but wasn't sure how you would like to handle the port.

[DaftMonk]

That's interesting, and I suppose that would make it more configurable from the Gruntfile. I'm just not sure if that level of configuration would be needed for most projects. If you can think of some specific uses cases for setting up the ports that way maybe we can change it.

[jeef3]

Agreed, most projects will be fine, hence not including it in this PR. The only use case I ran into was when I had LiveReload Sublime plug-in and running, it was conflicting with that port. I just leave this here as a note for the future perhaps 😄

[DaftMonk]

Well, it's something to consider for the future. Thanks for the PR!

Brilliant addition - great! Works like a charm!
