schemas/VegCore/VegCore.ERD.mwb: categories: fixed position of place to match where it now is in the diagram. lined up boxes so that there is a visible line between the place- and occurrence-related categories.

inputs/Madidi/IndividualObservation/map.csv: translated 1:many mappings ( FieldFamilyFullName->{family,originalFamily} ) to derived columns (in postprocess.sql) to work with new-style import, which must have a 1:1 relationship between input and output columns

schemas/util.sql: added reset_col_names(), the counterpart to set_col_names(). note that this alters the map table, so it will need to be repopulated after running this function.

schemas/util.sql: mk_derived_col(): support using this function to overwrite an existing column (i.e. as a general-purpose function to perform in-place update with ALTER COLUMN TYPE USING)

lib/sh/db.sh: psql(): display stack traces and DETAIL sections of error messages at verbosity 2+, to help debugging (previously they were always turned off). in particular, the DETAIL section of a "duplicate key value violates unique constraint" error is useful because it contains the duplicated key.

inputs/.TNRS/: switched to new-style import. because this does not have data subdirs (data comes from the TNRS client), this is just a matter of adding ./run.

inputs/.TNRS/Source/: switched to new-style import. this had been missed when all the Source/ subdirs were batch-switched to new-style import.

inputs/*/*/map.csv: replaced /_first filter with mapping to DUPLICATE special term (VegCore.vegpath.org?DUPLICATE). this removes collisions that don't need a postprocessing formula to combine the columns.

inputs/Madidi/map.csv: removed filters on columns from before the refresh (which are not in active use), so that they don't show up in a search for map.csvs with filters (indicating collisions)

inputs/Madidi/IndividualObservation/map.csv: SeniorCollector: don't prepend it to the CollectorString because the CollectorString already contains it. this may be a change between the BIEN2 and refreshed Madidi data (which uses a significantly different schema).
