Added canUseCache: function option.

Browse Source 
Check if this query can be autocompleted from cache, without ajax request.

Usage (directory autocomplete, do ajaxs only if "/" has been typed):
$(selector).autocomplete({
  ...
  canUseCache: function(query) {
    return query.length == 0 || query[query.length - 1] != "/";
  },
  ...
});
