    [WINLOGON] Fix shutdown timeout format string for long timeout
    
    - Use the "%d days" format for timeouts longer than a day.
    - Fail if timeout is 10 years or longer.
    - TODO: Replace format strings by resources. German WinXP uses "%d days"
instead of "%d Tage". We can do better! ;-)
