inputs/Madidi/Plot/map.csv: Remapped Latitude/Longitude (DMS) to new latitude_DMS/longitude_DMS

mappings/VegCore-VegBIEN.csv: Mapped latitude_DMS, longitude_DMS

mappings/VegCore.csv: Added latitude_DMS, longitude_DMS

inputs/REMIB/Specimen/map.csv: Remapped lat_deg/long_deg to decimalLatitude/Longitude because these values are (integer) degrees suitable for decimalLatitude/Longitude. Note that the other DMS fields are not yet translated to decimal degrees.

mappings/Veg+-VegCore.csv: Remapped latitude/longitude to decimalLatitude/Longitude because these fields almost always have units of decimal degrees

mappings/VegCore-VegBIEN.csv: Added empty mappings for special values (OMIT, etc.), so that they don't show up in **/unmapped_terms.csv. Note that the VegBIEN.csvs only change because the "No join mapping" errors change to "No non-empty join mapping".

input.Makefile: Maps validation: %/unmapped_terms.csv, %/new_terms.csv: Don't automatically regenerate the aggregated unmapped_terms.csv, new_terms.csv because this almost doubles the remake time when a mappings/ prerequisite changes (41s -> 75s)

mappings/VegCore-VegBIEN.csv: Added empty mappings for special values (OMIT, etc.), so that they don't show up in **/unmapped_terms.csv. Note that the VegBIEN.csvs only change because the "No join mapping" errors change to "No non-empty join mapping".

inputs/GBIF/Specimen/map.csv: Remapped VerbatimLatitude/Longitude to decimalLatitude/Longitude because DecimalLatitude/Longitude just contains VerbatimLatitude/Longitude cast to a low-resolution float, which created spurious repeating decimals

mappings/Makefile: .VegCore-VegBIEN.csv.last_cleanup: Generate VegCore-VegBIEN.unsourced_terms.csv whenever VegCore-VegBIEN.csv changes, to track VegCore terms that are mapped to VegBIEN but not documented in VegCore.csv. Note that this file is not svn:ignored, so it will show up with a ? when the user runs `svn st` if there are any unsourced terms.
