Dependency deprecation warning: gulp-util (npm)

On registry `https://registry.npmjs.org/`, the "latest" version (v3.0.8) of dependency `gulp-util` has the following deprecation notice:

`gulp-util is deprecated - replace it, following the guidelines at https://medium.com/gulpjs/gulp-util-ca3b1f9f9ac5`

Marking the latest version of an npm package as deprecated results in the entire package being considered deprecated, so contact the package author you think this is a mistake.

Affected package file(s): `mobile-web/package.json`

If you don't care about this, you can close this issue and not be warned about `gulp-util`'s deprecation again. If you would like to completely disable all future deprecation warnings then add the following to your config:

```
"suppressNotifications": ["deprecationWarningIssues"]
```

Start with mobile-web/package.json and inspect the gulp-util dependency version against the npm registry notice and the replacement guidelines linked in the issue. Done means the deprecated dependency has been replaced or otherwise addressed without the deprecation warning applying to this package.
