## User Story:
As a user I want to be able to favourite templates that I use frequently, so that I can recall them easily.
## Acceptance criteria:
* A new OOUI template search widget has been created in #TemplateData.
* The new widget is in use in both #VisualEditor and #TemplateWizard.
* The search experience in the new widget is the same as in both previous versions (both with and without #cirrussearch).
* An editor can see whether a template is a favourite via a new icon in the search results dropdown list.
## Details for QA:
* Test with all possible permutations of the above extensions being installed or not.
* Favourites are saved as a user preference.
