Code review

We have a newer version of application.js which should be used in all apps.

Please replace this file with the one found here: https://github.com/feedhenry-templates/welcome-cloud/blob/master/application.js

You will also need to update your package.json to reflect this one: https://github.com/feedhenry-templates/welcome-cloud/blob/master/package.json - note in particular  "fh-mbaas-api": "~4.0.0",
