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

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

added validation/aggregating/traits/BIEN2_traits/_archive/bien3_validations_traits_complete.sql from Brad's e-mail

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.

validation/aggregating/*/*.sql: renamed views to match the current naming scheme in the DB. these files still need to be kept up-to-date because there are some queries that haven't been implemented yet, and therefore exist only in these files, not the DB.

bugfix: validation/aggregating/traits/BIEN2_traits/bien3_validations_traits_original_mysql.VegCore.sql: added util to search_path so that IFNULL would link to util.ifnull()

validation/aggregating/traits/BIEN2_traits/bien3_validations_traits_original_mysql.VegCore.sql: added view names using the steps at wiki.vegpath.org/Aggregating_validations_refactoring#prepend-CREATE-VIEW
