Added inputs/IUCN/

input.Makefile: SVN: add: Added _src/ (when it exists). $(_svnFilesGlob): Added .url, .pdf files in _src/.

psql_vegbien: Use bash because it supports substitutions

psql_vegbien: Set the search_path to $out_schemas set by vegbien_dest. This will enable running any psql_vegbien script on a schema other than public.

schemas/vegbien.sql: analytical_stem_view: Changed inner joins on non-datasource taxonlabels to LEFT JOINs, to ensure that an entry is included in the analytical DB even if there was no matched taxonlabel. In theory, this shouldn't be necessary, because every taxonlabel should have a canonical taxonlabel since canon_label_id is auto-populated to the taxonlabel_id if there is no matched_label_id; there should be a taxonverbatim for every datasource and accepted taxonlabel because datasources link to taxonlabel via taxonverbatim and TNRS populates a taxonverbatim for every accepted taxonlabel; and there should be a parsed taxonlabel for every datasource taxonlabel because the mappings populate it.

schemas/vegbien.sql: analytical_stem_view: Removed join on specimenreplicate, because it isn't used in the analytical DB. Each specimen will still get an entry in analytical_*, because it gets its own location.

README.TXT: Data import: Before starting import, added step to run `make inputs/upload` and reinstall newly-uploaded datasources

README.TXT: Schema changes: Remember to update the following files with any renamings: Added mappings/verify.*.sql

README.TXT: Data import: make_analytical_db: Documented how to view progress in log file

make_analytical_db: Run all commands synchronously so the log file output doesn't become jumbled
