CVS commit by charles: 

Use calendar system specific date to calcuate week numbers, so week numbers
work for non-Gregorian systems as well. Tested on Gregorian, Hijri, Hebrew, 
and Jalali calender systems and seems to work fine.  At least Gregorian
works as before, but now the other calendar systems do as well.

This patch contributed by liucougar@gmail.com.  Thank you.
