Add a Logon screensaver similar to the one of Windows developed by Marc Piulachs (marc DOT piulachs AT codexchange DOT net)

I modified the code, so the screensaver is listed as "Logon ScreenSaver" instead of "Default ScreenSaver"

I also added the other screensavers we have to the Boot-CD.
Some of them highlight some bugs in ReactOS, when you try to use them.
See issue #2505 for more details.
