schemas/vegbien.sql: synced from DB, which changes the order of the ~type tables

schemas/util.sql: diff(regclass, regclass): support custom %== by including the col_type_null's schema in the search_path

schemas/util.sql: debug_print_return_value(): don't '-encode the value by default, because text values usually look better without the '-escaping

bugfix: schemas/util.sql: mk_set_search_path(): debug_print_return_value() needs to be on mk_set_search_path(text), not mk_search_path(VARIADIC text[])

schemas/util.sql: mk_search_path(): use debug_print_return_value() because this function is used with EXECUTE rather than util.eval() (in order to affect the calling function), so the search_path would not otherwise be printed

schemas/util.sql: added debug_print_return_value()

schemas/util.sql: diff(text, text): support custom search_path because custom %== operators are usually not in the util schema

schemas/util.sql: diff(text, text): renamed IN params to be different from OUT params to support LANGUAGE plpgsql

bugfix: schemas/util.sql: diff(*): changed from STABLE to VOLATILE because these functions create tables

/README.TXT: use full hostname for jupiter so the commands work outside of the NCEAS network as well
