* Evergreen rel_2_3 / master

The existing stock index for corporate authors only kicks in if the 710 subfield 'e' == 'creator', but relator codes (in subfield '4') are by many accounts a preferred mode of identifying the relationship of an added entry. Thus, add '4' == ('aut' or 'cre') to the criteria for indexing a corporate author.

Please see user/dbs/corporate_author for a branch with a simple change to the config.metabib_field stock definition and associated upgrade script.
