    * Quite a hack -- but my first attempt at a plugin.  We were
    * looking for a way to play a sound when there was unseen
    * messages to look at.  Nice for users who keep the squirrel
    * mail window up for long periods of time and want to know
    * when mail arrives.
    *
    * Basically, I hacked much of left_main.php into a plugin that
    * goes through each mail folder and increments a flag if
    * there are unseen messages.  If the final count of unseen
    * folders is > 0, then we play a sound (using the HTML at the
    * far end of this script).
    *
    * This was tested with IE5.0 - but I hear Netscape works well,
    * too (with a plugin).
