AlarmClockXtreme v1.15.27
Added rotating shift-pattern scheduling for DDNNO, 4-on-4-off, Panama, DuPont, and Pitman cycles.
Shift patterns can act as the recurring schedule by themselves or narrow existing weekday selections.
Alarm Edit exposes the preset and cycle start date; alarm cards show a compact shift chip.
Room schema is now v22 and backup format is now v16.
