[Koha-patches] [PATCH] Bug 6831: Add ability to enter adding child record from parent

[Colin Campbell]

Simplifies the adding of analytical records and ensures that
the data populating the 773 tag is correct. From the host record
add child record is selected and create bib is entered to generate
a new record with host item tag populated from the parent

Caveat: currently prepare_host_field only returns a field for
MARC21. Values for UNIMARC and NORMARC can easily be added but
should be done by someone familar with those formats
and conventions
