Log Message:
Fix race condition with concurrent instances updating stats files (?sts.*)

If you run multiple instances of sbbs sharing the same data files (I know you
don't) *and* you have more than one instance running the terminal server timed
events thread with "New day events" enabled (the default), you ran the risk
of more than one instance updating the various stats files at midnight and
racing with each other, e.g. (nodes 11, 6, and 1 are all different instances
of sbbs):

The "prev" date being in the future is an obvious check, but also
double-checking the date in the dsts.ini files after we open each for update
and log if the date is unexpectedly already set to today or the future.

This issue likely didn't effect anyone but Vertrauen, but I observed it when
scrutinizing 'slog' and SBBSCTRL->BBS->View->Statistics Log output and
noticed a stuttering in the logged dates, e.g.
