Fix recurrence rule expansion with ordered weekdayHEADmaster
When the order of a weekday in BYDAY rule expansion (like -5SA or 5SU for monthly or 55WE for yearly) exceeds the number of available weekdays in the period (month or year), rule expansion with negative order could result in a floating point exception. The reason: the modified frequency might become zero. Solution. Check order against number of available weekdays and terminate expansion early whenever possible (also for positive orders).
