[Swoop] Tiny fix for Linux

[Yarden Katz]

Hi,

  I was experiencing two problems with SWOOP on Linux: 1) icons didn't
  show up at all (e.g. back/forward arrows) and 2) bookmarks never
  loaded.  The fix was trivial.  For images to show up on Linux,
  you must include the images/ directory in build.xml, so the
  following block needs to be in there (it was commented):
  
        <!-- Copy in image files" -->
        <mkdir dir="${dist}/images"/>
        <copy todir="${dist}/images">
            <fileset dir="images">
                <include name="**/*"/>
            </fileset>
        </copy>

  and as far as bookmarks go... I just changed "Favorites.txt" to
  "favorites.txt", since Unix is case sensitive :).  The reason I'm
  announcing these changes here is because I don't know much about
  Java/ant, so I hope I didn't break anything.  But for what its
  worth, this completely fixed any problem I had with SWOOP on Linux.

Thanks,
