New FIRSTFDBK parameter in JTOPTS

The FIRSTFDBK parameter has been added to the JTOPTS statement. If you specify YES, every new job that you define in the AD database is updated with the actual duration at its first run, regardless of the estimated values. At the next run, the duration is updated according to the values that you set for LIMFDBK and SMOOTHING.
