Fix PRS1 F0V23 PB parsing bug that triggered unordered data warnings.

Browse Source 
A PB event obviously can't start so late that its duration ends in the future!
The fix hasn't been applied to F0V4 or F0V6 yet, since those haven't been
tested yet.

Also fix a sign bug in EventList::AddEvent when there *is* unordered data.
