I've cleaned up the go button code a little and moved it to a separate function. I've also changed the behavior to first try to find a close title match before running a full text search. That is, the process is now:

1) try various capitalization variants (we could make this simpler by creating an UPPER index in CUR, but it may not be worth it); if there's a match, display it 2) try title search in search index, if there's a match, display it (e.g. typing "Chomsky" and clicking go will also display "Noam Chomsky"); this searches across namespaces. In some cases it produces weird hits because it just picks the first match, so cunctator->go might put you on the talk page or on some subpage instead of the user page, depending on the order in the table. 3) run full text search
