Re-indent update-script.js
typo bug "includeDoc"

(the perils of using a dynamic language)
Improve SplitCategory update-script handling. Add JUL log file.
Mark 'source' as stored, so Solr data can be re-indexed without original input CSV.
Move CSV params to a new /updateGazCsv request handler
Refactor: Move logic name_type 'N' and 'A' shrinking to CSV map, out of script.
Fixed bad variable names and improved some comments.
Refactor: removed conditional debug in favor of SLF4J substitution
