validation/aggregating/*/*.sql: use current_schema instead of a hardcoded datasource name or psql variable

validation/aggregating/*/*.sql: search_path: added public

validation/aggregating/*/*.sql: use the new type-specific validation schema names

validation/aggregating/*/*.sql: removed type-specific prefix from the view name, which is now part of the validation schema

validation/aggregating/traits/bien3_validations_traits_bien3.sql: include only records from the bien2_traits datasource, to ensure that the scope of all queries is limited to the datasource

validation/aggregating/*/*.sql (the output queries): added `SET search_path TO validation`

validation/aggregating/traits/bien3_validations_traits_bien3.sql: added CREATE VIEW prefixes using the steps at wiki.vegpath.org/Aggregating_validations_refactoring#prepend-CREATE-VIEW

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.

fix: validation/aggregating/traits/_archive/bien3_validations_traits_bien3.by=Brad@iPlant.sql: renamed to indicate that this is actually not Brad's original file, as the filename would seem to indicate
