Count from the log again on Reset Serial Numbers

Browse Source 
The button started the numbers again at one. N1MM's manual says it "sets
serial numbers on all computers to the highest value in any of the logs,
plus 1", and its own handler re-reads the highest number per band out of
the log, so a mixed network came apart at exactly the point the button is
meant to repair: the N1MM stations counted on from the highest number and
this one started at one, sending numbers that had already gone out.

ContestSession.RestartNumbers fills the pool from the log, which is where
the reset now lands. SerialNumbersFrom is gone with it, and so is the pool
this station sent afterwards: N1MM sends none, because each station works
the same number out of its own copy of the log.
