If neither wxCAL_SUNDAY_FIRST or wxCAL_MONDAY_FIRST was given, use wxDateTime::GetFirstWeekDay() to automatically determine the preferred day. This changes the earlier default behaviour, which was to use Sunday if not otherwise specified. However, the wxGTK native calendar control ignored this behaviour anyway.
