lib/sh/util.sh: .(): put echo_func on its own line for clarity

lib/sh/util.sh: .(): added echo_func (2 log_levels up because it's internal)

schemas/VegCore/mk_derived: use new lib/sh/local.sh instead of lib/import.sh (a precursor to util.sh, etc. still used by inputs/FIA/)

bugfix: load_data(): verbosity_min: use verbosity_min='' so that csv2db's default verbosity (3) is used, instead of setting the verbosity directly to 3, which caused the log++ logging output from bin/make to be echoed at verbosity 3, creating cluttered output

lib/sh/util.sh: verbosity_min(): support value '', which sets verbosity=''

bugfix: inputs/GBIF/raw_occurrence_record_plants/postprocess.sql: updated column names to match the renamings in map.csv, which are now performed on the staging table itself

lib/sh/util.sh: run_args_cmd(): time the command so that the runtime of the outer runscript target (i.e. the command run from the shell) is printed at the end of the output, like in bin/make

bugfix: inputs/input.Makefile: %/install: don't run $(cleanup) if it has already been run by $(import_install_), so that it doesn't run twice

inputs/input.Makefile: %/postprocess: don't run postprocess.sql if it is supposed to be run by a runscript, because postprocess.sql may then depend on additional steps the runscript runs before it

lib/runscripts/table.run: import(): use self_make on load_data so that the remake status determines whether the table is reinstalled
