Bug 15971: Add biblioitems to available fields for serial claim notices and fix notices editor display

This fixes 2 related problems:

1) The editor only offered 3 entries from biblio for adding to the notice:
title, author, serial
It was not clear that actually all fields from biblio can be used.

2) It was not possible to use fields from biblioitems in the notices
which left out important fields like the ISSN.

The patch adds the biblioitems table and changes the editor to show
all entries from biblio and biblioitems table are shown on the left.

To test:
- Create a subscription
- Generate next issue a few times to get late issues
- Create a new notice in the "Claim serial issue" module
  - Use fields from different/all tables
- Make sure an email address is set for
  - the vendor (also check for 'receives claims for late issues')
  - your staff user
- Go to serials > claims
- Claim multiple issues
- Verify the email is generated and contains the correct information

Example notice:

Title: <<biblio.title>>
Author: <<biblio.author>>
ISSN: <<biblioitems.issn>>
ISBN: <<biblioitems.isbn>>
Issue: <<serial.serialseq>>
