bugfix: lib/sh/resume_import.sh: sed calls: moved end-of-line comments to their own line because end-of-line comments are not supported on Mac

lib/runscripts/table_dir.run: renamed table to subdir because this can apply to any datasrc subdir. moved table-specific code to table.run.

lib/runscripts/table_dir.run: renamed table to subdir because this can apply to any datasrc subdir. moved table-specific code to table.run.

lib/runscripts/table_dir.run: table_make(): moved $silent flag to lib/sh/make.sh make() so all make callers can use it

bugfix: inputs/GBIF/_MySQL/GBIFPortalDB-2013-02-20.data.sql.run: override ^.preamble.sql/make() and use ../_src/GBIFPortalDB-2013-02-20.dump as the dumpfile instead of this file, which does not contain the preamble

bugfix: lib/sh/resume_import.sh: $preamble_file: use the extension .0.preamble.sql instead of .preamble.sql so the preamble file sorts before the other *.sql files

removed inputs/GBIF/_MySQL/MySQL.data.sql*, since we are using the much faster exported TSVs instead (see raw_occurrence_record/table.tsv). this also avoids confusion between GBIFPortalDB-2013-02-20.data.sql* and MySQL.data.sql* when loading data into MySQL.

bugfix: inputs/GBIF/_MySQL/MySQL.data.sql.run: moved to GBIFPortalDB-2013-02-20.data.sql.run since it's actually the raw input file, not the ANSI export of it, that needs to be imported

lib/sh/resume_import.sh: get_pkey_at_pos(): changed $quote to ` to work with inputs/GBIF/_MySQL/GBIFPortalDB-2013-02-20.data.sql

lib/sh/db.sh: mysql(): added $log_queries flag, which can be turned off to avoid using --verbose. this is useful when running bulk INSERT statements.
