adding Yaqut data, first placeholders

updated publication date, added revisionDesc item, and added placeholder
bibl element to each place with Yaqut data.  Next step: enter the data
itself!
expanded Yaqut bibls, still no page numbers
refactored code spaces things differently
added Yaqut page numbers
added Yaqut citation to prior names

When a name already in the record was found in Yaqut, I simply added the
Yaqut citation to the source attribute of the placeName element.
added new Yaqut names, added # to citations

previously added citations were missing the # pointer
corrected new name xml:ids

if there were multiple new Yaqut names, the new name xml:ids were
missing the index number.
added Yaqut attestation
