inputs/.TNRS/schema.sql: Removed no longer needed tnrs_accepted_names index, now that the accepted names have been split into a separate table

inputs/.TNRS/: Split tnrs table into tnrs_accepted and tnrs_other, with tnrs_accepted imported first. This will eventually allow TNRS data to be imported without needing to use _taxonlabel_set_matched_label_id(), which is extremely slow due to an unknown bug in PostgreSQL's handling of UPDATEs on large tables (possibly limited to UPDATEs inside functions).

input.Makefile: SVN: add: Fixed bug where logs/*.log.sql was incorrectly being included in the list of files to put under version control

lib/common.Makefile: Filesystem: $(wildcard/): Fixed bug where {} exprs weren't handled correctly when some branches contained *, by using `shopt -s nullglob` and bash directly instead of trying to emulate it with grep

input.Makefile: Staging tables installation: `%/install: %/create.sql`: Also provide the schema to create.sql in :schema

bin/map: Added support for including literal metadata values in the map spreadsheet, by prefixing them with ':'

mappings/VegCore.csv: Added distanceToCountry_km, distanceToStateProvince_km

mappings/VegCore.csv: Added distanceToCountry_m, distanceToStateProvince_m

mappings/VegCore-VegBIEN.csv: Mapped acceptedCountry, acceptedStateProvince, acceptedDecimalLatitude/Longitude. Mapped decimalLatitude/Longitude to matched place's coordinates when acceptedDecimalLatitude/Longitude not provided (as is the case for the geoscrub table).

input.Makefile: SVN: $(svnFilesGlob): Added schema.sql
