OnDateSetListener does not pass Calendar corrected for minute interval

[nickdaugherty]

When implementing an OnDateSetListener for a DateSlider, the Calendar object that is passed to the listener's onDateSet method is not adjusted to the configured MINUTEINTERVAL. Instead, the normal date is returned, so you end up getting dates in between the interval, such as 5:10 when the MINUTEINTERVAL is set to 15.

Expected behavior is the Calendar returned matches the date chosen by the user, without having to do a

selectedDate.set(Calendar.MINUTE, selectedDate.get(Calendar.MINUTE)/TimeLabeler.MINUTEINTERVAL*TimeLabeler.MINUTEINTERVAL);

to correct it.
