[Koha-patches] [PATCH] Patch to improve auto-generated MARC21 authorities

[Brian Harrington]

This patch makes sure that MARC21 authorities have a minimal
Leader, 008, and 040.  If an authority record is created through
BiblioAddsAuthority it generates a 670 based on information in
the bib record.
