bugfix: inputs/SpeciesLink/Specimen/map.csv: dwc_terms_scientificName: remapped to scientificName instead of taxonName to match that DwC term name, as well as the mappings of other *scientificName terms

inputs/SpeciesLink/Specimen/map.csv: marked dwc_geospatial_VerbatimLatitude,Longitude as exact duplicates of dwc_terms_*

inputs/SpeciesLink/Specimen/map.csv: remapped identical _alt-ed fields to DUPLICATE. this avoids the need to translate these to postprocessing derived columns for new-style import, and also speeds up column-based import because there are less automatic _alts to perform to resolve filter-less collisions.

bugfix: inputs/SpeciesLink/Specimen/map.csv: *CollectorNumber: moved these to the same _alt group as recordNumber, because they are actually duplicates

correction: inputs/SpeciesLink/Specimen/map.csv: FieldNumber: fixed incorrect comment that these fields are identical to recordNumber, when instead they have the same *meaning but not the same values. instead, values are stored under either of the two terms. the previous conclusion had been based on an incorrect query, which used != instead of the NULL-sensitive IS NOT DISTINCT FROM.

planning/timeline/timeline.2013.xls: Adding derived columns: extended to overlap with all subtasks

planning/timeline/timeline.2013.xls: Geoscrubbing: split into separate re-run and automated pipeline tasks

planning/timeline/timeline.2013.xls: moved Data provider validations before Adding derived columns because ensuring that the source data is in the database is more important than the derived data, which can always be added later

planning/timeline/timeline.2013.xls: Data provider validations: added dot in July because some amount of datasource-level validation happens when mappings issues are discovered during the refactoring

bugfix: inputs/*/*/map.csv for specimen tables: remapped eventDate,day,month,year to *Collected, because a general date always applies to the observation itself rather than to any parent event (specimens don't have a parent event)
