    + Reintroduced: half-cooked console implementation of hbQT.
      This time it is targeted to provide a console widget inside 
      GUI MDI inetrface to run Clipper console code alongside GUI 
      controls. 

      DISCLAIMER: this is an effort and still don't know if I 
                  will succeed or be failure. But if I do succeed,
                  it will allow the migration of existing Harbour
                  console applications to GUI world easily. 

  * contrib/hbxbp/xbpparthandler.prg
  * contrib/hbxbp/xbpwindow.prg
    ! Fixed: error generated at after an owned XbpDialog() is deleted.
