validation/**.sql: replaced CREATE OR REPLACE VIEW with CREATE VIEW to match pg_dump output for diffing

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.

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

validation/aggregating/traits/BIEN2_traits/bien3_validations_traits_original_mysql.VegCore.sql: removed trailing whitespace

validation/**: removed old versions of by=-tagged files. these were not renamed in the last commit because there were newer versions that they collided with. note that because , sorts before . , the newer version (with more ",name@inst" tags) was correctly renamed instead of the older version.

validation/**: removed by=... indicators so that we don't have to add an author name every time a file is changed. the author indicator is not needed now that both Brad's and my edits are open-source.

validation/aggregating/*.by=Brad@iPlant*: placed under version control, since these are now open-source

validation/**: removed svn:ignore exclusion of iPlant-owned files, since these are now open-source
