Utils::CloseApplication should send WM_QUERYENDSESSION and WM_ENDSESSION

[wixbot]

Utils::CloseApplication is nice, but it should follow Restart Manager guidelines for closing applications. E.g., it should send WM_QUERYENDSESSION to determine if application supports closing, then WM_ENDSESSION in case it does and WM_CLOSE only as a fallback method.
This is described here: http://msdn.microsoft.com/en-us/library/aa373651%28v=vs.85%29.aspx

Currently, the custom action only sends WM_CLOSE message. This causes applications with "close to tray" ability to stay opened.
