[unhandled exception parsing "future dates" in some locales]

Browse Source 
There is already a check in the MonitoredDate class for years
which are more than one year in the future, so such a date is
already going to be shown in red.

But some locales use the "datetime" library to parse typed-in
dates and that has a maximum year of datetime.MAXYEAR, 9999
currently, so dates greater than that produce a ValueError.

Besides adding checks for that, I have also made it so that
locales which don't need that library don't use it.

Fixes #10815
