Fix "[ESE] Autocomplete" permission was not being checked for root-level autocomplete attempts
User's must have '[ESE] Autocomplete' permission in a global context, while '[ESE] Autocomplete' can be revoked per-forum.
Allow autocomplete links to be clickable
Add "last updated limit" to autocomplete & similar thread widget to support limiting by last update for threads/resources/Bob's AMS Articles
Requires re-indexing of resources & AMS Articles to enable this!
Add "Redirect to top validated suggestion" option.
If search result suggestion validation is enabled, a search with no results will redirect to the suggested search term with the most results.
