Unterrichtsplanung: Serienerzeugung, Stundenraster, Aufsichten & Vertretung (Kapitel 4.2/4.3 Nachtrag)

Stunden serienweise aus dem Stundenplan erzeugen (4.2.5); Stundenraster
(Uhrzeiten je Stunde) in den Einstellungen mit Zeitbedarf-Rückmeldung im
Verlaufsplan-Editor; wiederkehrende Pausenaufsicht; neuer "Vertretung
eintragen"-Dialog für einmalige Vertretungsaufsicht, Vertretungsstunde,
Sondereinsätze (Ausflüge, Berufsmessen) und schlichten Stundenausfall.
