fix: inputs/input.Makefile: add!: verify/: also svn:ignore .zip

fix: *Makefile: changed line endings to \n so that `patch` can work with pasted input. use `svn di --extensions --ignore-eol-style` to verify no diff.

fix: lib/sh/util.sh: already_exists_msg(): changed calling convention to avoid it seeming like `return 0` is run if already_exists_msg() throws an error, when in fact already_exists_msg() is just a command that should be run before returning/errexiting

inputs/GBIF/raw_occurrence_record_plants/test.xml.ref: updated

inputs/GBIF/_MySQL/.rsync_ignore: don't exclude GBIFPortalDB-*.data.sql.gz, even though this is an intermediate file, because it's better to have a backup of it locally. this was excluded in r13316 (2014-4-24) to free up disk space on the local machine.

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

*{.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.)
