Days of week are not localized

[bixbarton]

If you switch iPhone to French and use the duration picker, the days of the week are still showing MON, TUE, WED, THU, FRI, SAT & SUN.

You can add NSLocalizedString("MON", "LUN") to CXDurationPickerMonthView.m, line 232 approx.

NSArray *days = @[NSLocalizedString("MON", ""), NSLocalizedString("TUE", ""), NSLocalizedString("WED", ""), NSLocalizedString("THU", ""), NSLocalizedString("FRI", ""), NSLocalizedString("SAT", ""), NSLocalizedString("MON", "")];

If you start from Monday, though, you should also edit, in - (void)layoutSubviews, at line 124 approx.
and change int i = 1 to int i = 2, since Sunday is the first week of the day (so, 1)

for (int i = 2; i < self.components.weekday; i++) { colIndex++; }
