Comment 12 for bug 540490

New version of the 1.7 series patch.

    - Bring the Liferea window to front in liferea_shell_activate
      (makes indicators bring it to front if it is already open).
    - When an indicator is clicked, remove it and the draw attention status
      of other indicators, and block further indicator updates while the
      Liferea window is active.
    - For items with subitems (such as a feed source), show one indicator per
      each subitem separately.
    - Limit maximum number of indicators to 6 (MAX_INDICATORS).
