fix: validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: updated table names to match our renamings

schemas/vegbien.sql: public_validations.remake_diff_table(): put the type table in the public_validations schema to avoid cluttering up the datasource schema with internal tables

schemas/vegbien.sql: synced to DB, which changes the sort order (due to system update?)

bugfix: validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: can't double-JOIN like in MySQL (`JOIN a JOIN b ON a_conds AND b_conds`), so split double-JOIN into two JOINs w/ own ON clauses

added validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql, modified from bien3_validations_salvias_db_original.sql using the steps at http://wiki.vegpath.org/Aggregating_validations_refactoring

fix: /README.TXT: use exact ssh command needed to connect to vegbiendev/jupiter (eg. `ssh -t vegbiendev.nceas.ucsb.edu exec sudo su - aaronmk`) instead of vaguely referring to "on vegbiendev"/"on jupiter"

/README.TXT: Full database import: screen: run `unset TMOUT` first because it is most important, now that the remote servers have a TMOUT set for extra security

bin/psql_verbose_vegbien: use \\ instead of \ inside '' because this is sh, not bash

bin/psql_verbose_vegbien: changed prep-statement order to match lib/sh/db.sh psql()

bin/psql_verbose_vegbien: use `\set VERBOSITY terse` to hide stack traces/DETAIL sections of error messages, like in lib/sh/db.sh psql()
