Title: autocompletion plugin should change the input field value on navigation through the result list via key down/up.

The jquery autocompletion plugin changes the input field value on navigation through the result list via key down/up. This is what most other applications google, firefox, etc do.
It was explicitly disabled in rails3-jquery-autocomplete. This enabled it again
