title: Auto-focus feature for tag-it
body: <p>In the plugin tag-it from <a href="https://github.com/aehlke/tag-it" rel="nofollow">https://github.com/aehlke/tag-it</a> (demo - <a href="http://aehlke.github.com/tag-it/examples.html" rel="nofollow">http://aehlke.github.com/tag-it/examples.html</a>), how is it possible to add the autofocus (i.e If set to true the first item will automatically be focused when the menu is shown) feature in the jquery - tag-it.js?</p>
  
  <p>EDIT: The feature should also enable the suggestion to be inputted or made appear in the input box when 'Enter key' is hit.</p>
