Act on the .udc session, off-time and band-change settings

Four settings were read by nothing. MultipleSessions = 0000/30 runs the contest in half-hour sessions from 00:00 UTC. The session is part of the dupe key, so a station worked in an earlier one may be worked again, and ResetMultsEverySession and ResetSNEverySession start the multipliers and the serial numbers over. DupeQSOMinutesAgo is the other way back to a station: after so many minutes rather than in the next session. The log holds the time of the last contact per dupe key instead of only the key, and the setting's IgnoreBand and ThisMode decide the scope, because a file that uses it turns DupeType off. MinimumOffTime drives the time on and time off the score summary now shows under the score, and beside them are the band changes made against the allowance for a contest that limits them. N1MM's countdown for the minutes you have to stay on a new band needs its info window and is not here. UdcFile.Flag now takes 1 and 0 as well as True and False, which is what these settings are written as and what N1MM reads.
