haiku/src/kits/shared/CalendarView.cpp
Oliver Tappe 6846765fbf Work on #7947 (CalendarView not respecting locale's start of week)
* 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
