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): `package.json`, `tools/gulp-replace-important/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"]
```

Inspect the dependency entries in package.json and tools/gulp-replace-important/package.json, starting with the gulp-util references. Follow the linked gulp-util replacement guidelines and verify that the affected package files no longer produce this deprecation warning.
