Expand/Collapse all comments texts, for threaded comments v2

You must have threaded comments v2 installed for this to work. Edit blog template, expand widget templates, find lines:

<b:includable id='comments' var='post'>
  <div class='comments' id='comments'>
    <a name='comments'/>
    <b:if cond='data:post.allowComments'>
