Before this commit the search bar was specific to products.
After this commit a generic search bar is available as a general feature
of website which can be configured to inspect specific models.
The snippet is used to replace the old search bar in blog, courses,
event, forum, page and shop.
The search results of these pages and the autocomplete of the search bar
run through the same search mechanism.
A new hybrid results page has also been created as a target of a search
on "Everything".
In each involved module, `website._search_get_details()` is implemented
to return search metadata for every model related to the `search_type`
parameter.
Search metadata for a single model is returned by `_search_get_detail()`
on that specific model.
The autocomplete runs through the additional
`website._search_render_results()` pre-rendering step that prepares the
data to fit in the autocomplete template.
