  Function: RefreshManouverSet

  Purpose:  Refresh the local tank's maneuver set after each use, to deal with
            situation of focus lost of the main game dialog.

  Input:    None.

  Output:   None.

  Remarks:  When the game loose it's focus, the WM_KEY_UP message may be missed,
            thus causing the tank to repeat it's last maneuver set. To eliminate
            this phenomena, we check the key board state after every use of the
            maneuver set by the local tank.
