        * TimeZoneInfo.cs: Applied patch from Vincent Povirk that adds
        support for reading time zone information on windows.

        This patch makes TimeZoneInfo.GetSystemTimeZones and
        FindSystemTimeZoneById work based on the registry on non-Unix
        platforms, if the appropriate registry key exists. Mono currently
        reads from /usr/share/zoneinfo, which doesn't exist on Windows.

        This should fix bug 606084.

        It won't fix the Local property on Windows. I think that requires
        a Windows API call to get the id of the local timezone.

        This was modified from the previous version to not check the
        registry on Unix platforms. (Sorry it took me so long to do
        this. I have very little time to spend on Mono-related work.)
