Enhances an existing feature.

• What is the current behavior?

board listall, core search and lib search all use fuzzy search logic to find matching results, this is often unreliable and might either return few results or too many depending on the query string.

• What is the new behavior?

Fuzzy search logic has been removed in favor of the same logic used by board search, that has been taken from the library search dialog of the Java IDE with some improvements to handle unicode accents and other diatrics.

This way all searchable commands share the same logic and are more reliable.

This also affects the gRPC interface.

• Does this PR introduce a breaking change, and is
  titled accordingly?

Nope.

• Other information:

None.
