Subject: [PATCH] overview: Provide public access for search provider
 registration

Provide a reasonably public way to register and unregister search
providers, without adding too much API.

`Main.overview.searchController` provides access that may be generally
useful, while `SearchController.addProvider()` and
`SearchController.removeProvider()` provide a simple interface for
extensions.
