title: remove all selections from Jquery chosen plugin
body: <p>I am using Jquery <a href="http://harvesthq.github.com/chosen/" rel="nofollow">chosen</a> plugin for Multiple Select. I have to add a Reset button to clear all the selected items but not sure where to proceed.<br>
  Already tried <code>.clear</code> <code>.val([])</code> on it but nothing helped. How do you clear all the selected items?
  Plain javascript pointers would be helpful over jQuery based.</p>
