[DESK.CPL]
-Improve the hack that lets it process arguments by using the process command line instead
of the one shell32 gives to the cpl.
-Implement a new action called ActivateMSTheme that activates an msstyle file without
showing any gui. If no file is passed, the classic theme is activated thus making it
possible to switch themes from command line (or any other application may need to switch
themes by launching desk.cpl).
