get node-webkit version from in an app

[ibdknox]

I couldn't find a way to get the current version of node-webkit from within the app itself - this would be useful for update mechanisms that need to catch when someone has an old binary.

You can get current version with process.versions['node-webkit']

Thanks. There should be document on this. reopen to track the document.
