Web IDE as an app! (node-webkit / nw.js)

I just got the Web IDE working with node-webkit (now nw.js) - which means that soon it'll be available as a native (downloadable) app on Windows/Mac/Linux!

I don't have any packaged versions yet (all I have is x64 Linux, which I bet won't be helpful for many of you!) - unfortunately as it needs the platform-specific node-serialport library I have to work out how to include a build of that for each platform in the package (I wonder if anyone can help here?).

For now, to make your own package you need to:

• Install node.js and npm
  
• Install node-webkit with sudo npm install -g nw
  
• Download the gh-pages branch of the Web IDE
  
• Make sure the EspruinoTools submodule was in there (afaik it should be)
  
• Install the serialport module with npm install serialport - it turns out there's a bit more to it (see extras/create_nodewebkit.sh for the magic commands)
  
• Run extras/create_nodewebkit.sh
  
  

And you now have a node-webkit package that you can run with nw extras/espruino.nw - and it should work just like the normal Web IDE - except hopefully with a working serial port :)
