Allow partial terms and multiple search tokens instead of rigid 'begins-with' substring matching. This isn't perfect and could probably do with some tuning of the [FuzzySearch](https://github.com/jeancroy/FuzzySearch/blob/36e3ca507d0712af01f07a61f9734bfe22f281b6/dist/FuzzySearch.js#L27) parameters, but it's better than the current, very unforgiving, method. It also adds the `.php` suffix to selected autocomplete results (to match the canonical tags), stops the results list from becoming inaccessible when taller than the viewport, and drops a couple of unused variables.
