Change to use jQuery Autocomplete newer version and adjudge styling
Make module name to be a link
Add link to Task::Kensho on home page
Tweak settings for new jquery autocomplete

Avoid needless queries but do more to get better results.
Remove duplicate up/down arrow functionality

since the new plugin handles this natively.
Disable mouse movement select on autocomplete

I think selecting a choice on hover (but then requiring keystrokes)
is unintuitive and disabling that means there's no issue with prior mouse placement.

Fixes #774.
Fixes #993.
