schemas/vegbien.ERD.mwb: synced to schemas/vegbien.my.sql, which adds the validation schema

schemas/util.sql: added diff_views()

schemas/util.sql: added diff_cols(), for use with the aggregating validations

bugfix: schemas/Makefile: public/uninstall: need to uninstall the validation schema in addition to the public schema (deleting the public schema would only cascade to the contents of the validation schema)

schemas/vegbien.sql: added validation schema, which contains queries used in the aggregating validations. schemas/Makefile: include schemas that depend on `public` (eg. `validation`) so they are restored along with it.

bugfix: bin/pg_dump_vegbien: fixed arg-count check to allow passing command-line options to pg_dump via args

bugfix: inputs/SALVIAS/verify/plots.out.sql: fixed ' quoting syntax to use '' instead of \' to escape '

inputs/input.Makefile: verify/%.out: use a *.sql file in the verify/ directory itself to generate *.out, so that each datasource can have its own set of output queries. for datasources that should share the same set of queries, they can instead be symlinked to the same file.

fix: inputs/CVS/project/: added _no_import since this should not also be imported separately from taxon_observation.**

fix: validation/aggregating/traits/_archive/bien3_validations_traits_bien3.by=Brad@iPlant,Aaron@UCSB,Brad@iPlant.sql: added missing .url extension
