new data run with new dates

To allow me to see what changes as I tweak the XSLT
added empty abstract placeholder note

To allow xquery to find the right place later
added "syriaca-anglicized" tag to "Other en-" names
removed "syriaca-anglicized" from duplicate names

Sometimes the name in the "Other en-" column was also contained in
another column, sometimes even the GEDSH or GS columns.  This was
replacing "syriaca-headword" with "syriaca-anglicized," and was marking
names from CBSC or Barsoum as "syriaca-anglicized."  I removed
"syriaca-anglicized" from these names and only applied it to names which
only exist in the "Other en" columns.
add Syriac headword to article title

<title> in <titleStmt> in header was only English headword; now it
includes Syriac heaword.
add Barsoum century when it's the only date

encode it as a floruit
