validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `CREATE OR REPLACE VIEW` so the validations views are not unintentionally replaced when running this file

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: updated from DB

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 .

fix: validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: renamed truncated views to match the output queries

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

validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: removed `LIMIT 10` to match output queries

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

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

validation/aggregating/*/*.sql, schemas/vegbien.sql, lib/runscripts/validations.pg.sql.run, inputs/bien2_traits/validations.sql: added _ to beginning of each view name so the validation views would sort at the top in the datasource's tables list. this will also make the validation result sets easily distinguishable from the data tables.
