inputs/GBIF/table.run: table.tsv.md5/make(): only use %-remake if remaking

lib/sh/make.sh: make(): removed extra space after --silent

lib/sh/db.sh: moved mysql_root() after the mysql->mysql_ANSI alias (and load new aliases) so that it will also use ANSI mode and support "" identifiers

lib/sh/db.sh: mysql: always use ANSI mode, to support "" identifiers. note that `` are still supported in this mode, so it also works with SHOW CREATE TABLE output and dumpfiles.

bugfix: inputs/GBIF/raw_occurrence_record/run: plant_fraction_for_herbaria_filter/make(): need to make prerequisites first (plant_fraction/make)

bugfix: inputs/GBIF/table.run: table.tsv.md5/make(): use %-remake to ensure that the .md5 file is remade, regardless of the .md5 file's mtime relative to table.tsv. you would generally expect table.tsv's new mtime to be newer than the .md5 file's (thus triggering make to run), but if you e.g. ran svn up after making the table.tsv, this might not be the case.

/Makefile: moved %/remake, %-remake to lib/common.Makefile because they are generally useful

/Makefile: moved %/reinstall to lib/common.Makefile because it is generally useful

lib/sh/db.sh: mysql_cmd(): run the command with `time` because in mysql()'s output_data mode, no queries, and therefore no runtimes, are echoed, so the total runtime needs to be echoed separately instead. the total runtime is also useful in general, when many long-running queries are run and you would also like to know the total time (e.g. in make_analytical_db).

lib/sh/db.sh: limit(): usage: surrounded query in "" to clarify that it's a string, not a command
