added backups/TNRS.2014-6-2.backup.md5

_license/non-open-source/applies_to.txt: clarified that the things in this list are not embargoed, the issue is just that they are not formally open-source

schemas/public_.sql: view_full_occurrence_individual_view: join to taxonoccurrence: can use a USING join for this because plot.** only exports one locationevent_id column

inputs/Cyrille_traits/trait_observation/postprocess.sql: accessRights index: added vegbiendev runtime

fix: inputs/Cyrille_traits/trait_observation/postprocess.sql: need to remove private data, as clarified by Cyrille

inputs/publishable datasources.xlsx: updated: Cyrille traits: updated with Cyrille's clarifications on publishability

bugfix: lib/sh/sync.sh, db.sh: *_snapshot() commands that run multiple sudo commands: use become_sudo so that the program won't hang at later sudo prompts. for pg_snapshot() with pg_start_backup(), this also prevents the backup from staying open at the end waiting on a sudo prompt, causing excess WAL logs to accrue.

lib/sh/util.sh: become_sudo: documented that this is for funcs that run multiple sudo commands

lib/sh/util.sh: $sudo_cmd_wrapper: use esc() so this does not need to be embedded with [@] array notation
