added Yezidis to place/1399 and place/2504

place/2504 refers to the main Yezidi shrine in Lalish, which according
to a Syriac text forged in the 19th C was originally a monastery (but
this is false).  I added a wikipedia link and Yezidi confession to
Lalish (place/1399), and added the name of the Yezidi shrine and
abstract to place/2504, changing its type from 'monastery' to 'temple'
fixed confessions.xml URI in places 78, 168, 602

The confessions.xml URI included in Edessa (place/78), Rabban Hormizd
(place/168), and Kerala (place/602) was
http://syriaca.org/confessions.xml rather than
http://syriaca.org/documentation/confessions.xml as it should be.  This
has been fixed.
