validation/aggregating/specimens/**.sql: removed trailing whitespace, using the steps at wiki.vegpath.org/Aggregating_validations_refactoring#translate-to-Postgres

archived validation/aggregating/specimens/NY/qualitative_validations_source_db_NYBG.sql

added validation/aggregating/specimens/NY/qualitative_validations_source_db_NYBG.VegCore.sql, copied from qualitative_validations_source_db_NYBG.sql

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

added validation/aggregating/, containing folders for Brad's scripts (the scripts themselves cannot be in the repository because they are not UCSB-owned)
