* BDate setters don't perform any validation, use with caution.
* BCalendarView setters do perform validation checks, and will adjust
the day so it fits the requested month or year.
* Add tests for the BCalendarView setters.
* There is a little code duplication. This will be moved to BFormat once
the time and datetime formatting is also moved out of BLocale
* The way to create a BDateFormat from a BLocale is still open for
discussion. I'm undecided between making BDateFormat a member of
BLocale, or adding a BDateFormat(const BLocale&) constructor.
* Adjust all users of the API.
* support all weekdays as start of week, not only Sunday and Monday
(at least Saturday is used for real, too)
* introduce BWeekday as enumeration of weekdays (currently in Locale.h,
may be moved somewhere else later)
* change CalendarView to use BDate as its model, not individual values
for day, month and year, such that no more date computation is done
in CalendarView itself
* some more style cleanups in CalendarView along the way
* add monthwise paging to CalendarView
* adjusted Deskbar and Time preflet accordingly

* determine first day of week and draw calendarview accordingly
* some cleanup: drop superfluous DateTimeView::Draw()
* automatic whitespace cleanup
