Pass gaze opts

This allows passing down options to gaze when using `gulp-watch` - we needed it for watching globs with more than 10 groups and increase the `maxListeners`, e.g. avoid:
```console
(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
```
