Title: added match event to allow for listening for recommendation changes

There are cases where people might want to listen in on a change to the autocomplete suggestion. This allows someone to use typeahead for instant search results with something along the lines of...

$('.typeahead').on('typeahead:match', function(e, match) {
updateResults(match);
});

As the recommendations change the results would then change.
