Add relationship of 'friend of' to HebrewCalendar.php

[gzh1960]

In HebrewCalendar.php can you add a relationship of 'friend of' as mourners sometimes want their dear friends who has passed on to be called and this is not catered for from what I can see in the code.

You can handle this yourself by adding a relationship type called "friend of"
