added inputs/GBIF/_src/0001000-131106143450413.zip.header.txt, which is useful to see what fields will be available when we switch to the new GBIF export format

*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)

lib/sh/make.sh: self_make(): renamed to with_rm() for clarity, since this is used only to progagate $rm, and does not also invoke a command with the same name as the current function, as the name might suggest

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).

inputs/XAL/Specimen/header.csv: updated

added inputs/NY/validations*.sql*
