- All the dev dependencies were updates in package.json.
- prepublish was replaced by prepare to fix "warn prepublish-on-install As of npm@5, `prepublish` scripts are deprecated" & "warn prepublish-on-install Use `prepare` for build steps and `prepublishOnly` for upload-only."
- node-sass was added in package.json and a require('node-sass') was added to Gruntfile.js since the new version of grunt-sass requires it (see: https://github.com/sindresorhus/grunt-sass/releases/tag/v3.0.0)
