inputs/input.Makefile: Staging tables installation: $(logInstall): don't output to the install log if $noclobber flag is set, to prevent overwriting the log when re-running the install target idempotently

bugfix: lib/runscripts/mysql.table.run: import(): move previous versions of table.tsv out of the main dir before loading staging tables, to prevent them from being considered a TSV segment file and prepended to table.tsv

lib/sh/util.sh: added mv2dir(), mv_glob which wrap mv

lib/sh/util.sh: added mkdir alias which adds -p to prevent errors if the dir already exists

lib/sh/util.sh: added wildcard alias, similar to make's $(wildcard) function

bugfix: inputs/GBIF/raw_occurrence_record_plants/postprocess.sql: institution_code index: create it idempotently using create_if_not_exists() and an explicit index name, so that a duplicate index doesn't get added each time postprocess.sql is run

lib/sh/local.sh: psql(): don't put util in the search_path because psql scripts now add it themselves if they need it, using `SELECT util.search_path_append(util);`

inputs/GBIF/raw_occurrence_record_plants/postprocess.sql: add util to the search_path so that postprocess.sql will also work when run by inputs/input.Makefile, which only puts the datasource (GBIF) in the search_path

schemas/util.sql: added search_path_append()

schemas/util.sql: added eval() to allow running EXECUTE outside of a function (and to echo the command that is run)
