  this code permit to manage 3 informations panels with one text area (or 2 if
  extended description plugin is used)

  this function don't use a regExp object (due to some freeze with this method
  during test)

  known tags :
    <!--up-down-->
    <!--right-left-->

  if the plugin "ExtendedDescription" is installed, the "<!--up-down-->" tag is
  already managed by the plugin :
    - top text is in a <div class="additional_info">
        => text is moved to the to the '#additional_infoTOP' div  and
            the '.additional_info' div added by the plugin is deleted
    - bottom text is in <div id="additional_infoLEFT">
        => if tag "<!--right-left-->" is present
            text on right is moved to the to the '#additional_infoBOTTOM' div and
            removed from the '#additional_infoLEFT' div

  if the plugin "ExtendedDescription" is not installed, all the text is in
  the <div id="additional_infoLEFT">
    => if tag "<!--up-down-->" is present
        text on right is moved to the to the '#additional_infoTOP' div and
        removed from the '#additional_infoLEFT' div
    => if tag "<!--right-left-->" is present on the '#additional_infoLEFT' div
        text on right is moved to the to the '#additional_infoBOTTOM' div and
        removed from the '#additional_infoLEFT' div
