    [MSGINA] Implement ShellTurnOffDialog (#3254)
    
    Based on the following prototype:
http://diendan.congdongcviet.com/threads/t13622::tim-handle-cua-cua-so-tat-…
(line 32) and return ShellShutdownDialog from it with all required parameters.
    It allows to open the shutdown dialog properly from the Start menu with shell32.dll
from Windows Server 2003 SP2 (when installing ReactOS as Workstation).
