Title: Tuples instead of sets

can anyone review this change? TRIGGER WARNING: it changes at least the ``holidays`` method output.
Now ``holidays`` returns a two-item-tuple list composed of the date and the label. Please note that this list is sorted. For quick search in "non-work-day", you may want to use the ``holidays_dates`` method.
