validation/aggregating/plots/_archive/bien3_validations_salvias_vegbien.by=Brad@iPlant.sql.url: removed trailing @
validation/aggregating/plots/bien3_validations_salvias_vegbien.by=Brad@iPlant.sql.url: moved to _archive/ so only the most recent version would be in the main plots/ directory
added validation/aggregating/, containing folders for Brad's scripts (the scripts themselves cannot be in the repository because they are not UCSB-owned)
