some progress on #79: don't display Bereshit incorrectly at the end of the year.
We were previously walking off the end of an array, which is not good...
A little more work is required to display Ha'Azinu or Vayeilech - this would deviate
from the algorithm provided by emacs cal-hebrew.el
fix #79: properly display Parashat Vayeilech or Ha'Azinu
