speedup plus potential bug fix

    in display_signature()
    there are calls to
    imagepng($image);
    imagedestroy($image);
    that are needless, since the image is already created you can just do this:
    $fp = fopen($folder . $imagename, 'rb'); # stream the image directly from the cachefile
    fpassthru($fp);

    instead of reprocessing it thru GD. (this was taken from PHP.net here: http://php.net/manual/en/function.imagepng.php)

    Also we had a bug where ob_start had previously been called. So we needed to clean the output buffer first.
    this will clean out all the buffers:
    $levels = ob_get_level();
    for ($i=0; $i<$levels; $i++)
    ob_end_clean();
