fix: schemas/public_.sql: viewfulloccurrence_individual_view_modify(): fixed capitalization in function name (needs "" to preserve case)

schemas/public_.sql: validation views: use analytical_stem_view instead of analytical_stem because analytical_stem is no longer materialized (viewFullOccurrence_individual_view is materialized instead)

schemas/public_.sql: derived views: use analytical_stem_view instead of analytical_stem because analytical_stem is no longer materialized (viewFullOccurrence_individual_view is materialized instead)

bugfix: schemas/util.sql: expansion_min_cols(): increased to properly handle all public-schema views (the largest is currently 2014-6-12.Jeff_Ott.climatic_range_determinants)
