Figure out how to load package.json without blowing up when releasing on OSX

[officert]

If you look at

https://github.com/officert/mongotron/blob/master/src/config/appConfig.js

you'll see our package.json is commented out:

// var packageJson = require('../../package.json');
var packageJson = {
  version: '1.0.0-alpha.1',
  name: 'Mongotron',
  repository: {
    url: 'https://github.com/mongotron'
  }
};

If you require the package.json file when running locally it works fine using a relative path. But if you package and release the app (using gulp-release-osx) you'll find that when you try and run you get a runtime error because electron can't find the file.
