Subject: [PATCH] Fix #3214: Add autocomplete for saved searches.

* Autocomplete the `search:<label>` metatag.

* Make label autocompletion do a prefix match instead of a substring
  match. Example: `search:ar` matches `artists`, not `characters`. This
  is how tags and most other things are autocompleted.
