* Issue: In BCalendarView presently, there is no notion of a current date
and the current date is not highlighted. So in the deskbar tray calendar
which uses BCalendarView, we cannot know the current date once we change
the selected day.
* Fix: Make BCalendarView accept pulse messages, check for system date
with every pulse message and update the current date accordingly.
Highlight the current date by rendering its day number text in a
different color.
