inputs/GBIF/_MySQL/.rsync_ignore: added GBIFPortalDB-*.data.sql.gz, because these are intermediate files

added inputs/GBIF/_src/0001000-131106143450413.zip.header.txt, which is useful to see what fields will be available when we switch to the new GBIF export format

added inputs/GBIF/_src/0001000-131106143450413.zip.header.txt.run

*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)

lib/sh/make.sh: self_make(): renamed to with_rm() for clarity, since this is used only to progagate $rm, and does not also invoke a command with the same name as the current function, as the name might suggest

schemas/vegbien.sql: specimenreplicate.institution_id: renamed to duplicate_institutions_sourcelist_id, as decided in the conference calls (wiki.vegpath.org/2014-03-13_conference_call#schema-changes-2)

mappings/VegCore.htm: regenerated from wiki: rename specimenHolderInstitutions to specimen_duplicate_institutions, as decided in the 2014-03-13 conference call (wiki.vegpath.org/2014-03-13_conference_call#schema-changes-2). note that most schema changes (such as this one) involve mappings changes, which are handled automatically by `inputs/run postprocess; yes|make inputs/{NVS,SALVIAS,TEAM}/test`.

bugfix: inputs/GBIF/table.run: switched to using lib/runscripts/table.run instead of mysql.table.run because some subdirs (Source/) need the regular table.run to work properly. mysql.table.run should instead be used directly by subdirs that use the MySQL install.

*{.sh,run}: use new begin_target instead of `echo_func; set_make_vars`

bugfix: *.sql: public.source_by_shortname(): need to wrap it in a nested SELECT because Postgres incorrectly does not constant-fold (inline) it, leading to a slowdown when it is therefore run many times. this is done using the steps at wiki.vegpath.org/Postgres_queries#wrap-function-call-in-nested-SELECT .
