validation/aggregating/specimens/qualitative_validations_specimens.sql: use taxonoccurrence instead of location as the table that all specimens should have, as decided in the 2014-03-27 conference call (wiki.vegpath.org/2014-03-27_conference_call#aggregating-validations)

lib/runscripts/util.run: support conventional main() method as well as `all` target

fix: inputs/*/*/map.csv: remapped occurrenceID-mapped fields to dataProviderRecordID when these were not globally unique DwC occurrenceIDs (http://rs.tdwg.org/dwc/terms/#occurrenceID)

fix: inputs/CTFS/AggregateObservation/map.csv: field mapped to occurrenceID: remapped to aggregateOrganismObservationID because these are not specimen occurrences

fix: mappings/VegCore-VegBIEN.csv: taxonoccurrence.sourceaccessioncode: need to populate from aggregateOrganismObservationID when only that is available

bugfix: inputs/NY/Ecatalog_all/map.csv: can't use CatalogNumber as pkey because it's not unique and not always populated. this fixes the NY NULL accessionNumbers bug (wiki.vegpath.org/Aggregating_validations_status#bugs).

/README.TXT: moved "to back up e-mails" and "to back up the version history" before settings backup so that the local backup of these is up to date when everything gets backed up

inputs/XAL/Specimen/header.csv: updated

/README.TXT: to synchronize vegbiendev, jupiter, and your local machine: backups/TNRS.backup: do this before the general sync so that any reverse sync that's needed won't include it

/README.TXT: to synchronize vegbiendev, jupiter, and your local machine: backups/TNRS.backup: use bin/sync_upload now that this works for rsync-ignored files
