/README.TXT: Full database import: make inputs/{upload,download}: run them first with `test=1` to see what the changes will be

/README.TXT: Full database import: `svn up`: use --force to avoid errors about existing files

mappings/VegCore-VegBIEN.csv: genus->taxonlabel.taxonomicname: filter out genera that contain numbers (using new _filter_genus()), which break TNRS and prevent it from matching any other parts of the name. later, these genera can instead be moved to the end of the name, where TNRS will correctly match them as Unmatched_terms.

bugfix: inputs/VegBIEN/: added _no_import to disable import for this folder, since this is actually just an entry in web/datasources/ with VegPath redirection links, rather than an input to the import process. this fixes "schema "VegBIEN" does not exist" errors generated in `make test`.

inputs/input.Makefile: $(dontImport): also support putting a _no_import file at the top level in the datasource to exclude the entire datasource

bugfix: lib/sh/local.sh: removed make() override, which is no longer needed now that its operations are performed by verbosity_compat(), and which caused errors by setting $verbosity to the invalid value ""

bugfix: lib/sh/util.sh: verbosity_compat(): always use default verbosity (`unset verbosity`) when verbosity == 1, regardless of whether the caller has set $verbosity to the special value "", because $verbosity is supposed to be an integer field and "" is not supported by most functions that use $verbosity. in cases where a util.sh script is invoked, it will set $verbosity back to the default value 1, so this will function as before for util.sh scripts and fix $verbosity for scripts that use a different verbosity system.

inputs/GBIF/raw_occurrence_record_plants/test.xml.ref: regenerated. updated for new staging table input columns, which are now the same as the output columns.
