[EXPLORER]
- Handle TWM_DOEXITWINDOWS in CTrayWindow. This message is sent from CDesktopWindow when it handles alt+f4 as an accelerator.
- Also handle SC_CLOSE for WM_SYSCOMMAND by calling ExitWindowsDialog.
- Fixes pressing alt+f4 in xp
- Now we have to make CDesktopWindow send TWM_DOEXITWINDOWS to the tray
