schemas/vegbien.sql: _specimens_13_count_of_all_verbatim_and_decimal_lat_long: ran through pipeline

fix: schemas/vegbien.sql: _specimens_12_distinct_collector_name_collect_num_date_w_count: dateCollected: also need to convert to text in GROUP BY/ORDER BY

bugfix: inputs/NY/validations.sql: _specimens_03_list_of_verbatim_families: use family as specified in query description, not as implemented

_license/UCSB/LICENSE.TXT: use (c) verbatim from the e-mail, not as displayed as © by Thunderbird

bugfix: schemas/vegbien.sql, inputs/NY/validations.sql, validation/aggregating/specimens/qualitative_validations_specimens.sql: _specimens_12_distinct_collector_name_collect_num_date_w_count: dateCollected: cast this to text rather than date because some values for this field are not valid dates and will throw an error if cast to date

fix: inputs/NY/validations.sql: _specimens_12_distinct_collector_name_collect_num_date_w_count: dateCollected: matched type to output query

validation/aggregating/pipeline/aggregating_validations_pipeline.odg: show that the staging table(s) are denormalized before running the input queries on them. clarified that what is compared are the input and output query results, not the queries themselves.
