[Javascript] Code optimization

[Mike Dougherty]

Is there a reason why the "filelist" is not marked up as a list?

  <ul id="filelist">
   <li class="NOR PRI DIR" id="images"><a ...><img>1</a></li>
   <li class="NOR PUB TXT" id="bugs.txt"><a ...><img>2</a></li>
   <li class="SEL PRI PDF" id="bugs.pdf"><a ...><img>3</a></li>
   <li class="NOR PUB MOV" id="bugs.mov"><a ...><img>4</a></li>
  </ul>

or maybe
   <li class="NOR PRI DIR" id="images">
     <a href='image_clicked'><img></a>
     <a href='text_clicked'>1</a>
   </li>

Forgive me if this is unrelated to the issue; I was not paying much attention earlier.
