Provides a loading indicator to show while the new Vue.js based
search widget loads. Given that the new widget will pull down the
entire Vue.js runtime, it's likely that there will be a delay
before the search suggestions appear. This loader is meant to
improve the perceived loading experience of the new widget.
Adds:
- New searchLoader.js file containing loading behaviour.
- This overrides the code searchSuggest loading behaviour.
- New SearchBoxLoader.less file containing the loader styles.
- i18n message: 'vector-search-loader'.
- The Event type to jsdoc.json
