Bug 14332: Skip articles in MARC21 using indicator n.2 of field 245

 Bug 14332: Skip articles in MARC21 using indicator n.2 of field 245

Only in MARC21 is possible to use ind2 of tag 245 to skip articles.
This patch is based on inserting a special template in
koha-indexdefs-to-zebra.xsl With this patch you must not insert index
Title:s in biblio-koha-indexdefs.xml, it is defined in
koha-indexdefs-to-zebra.xsl.  It is not the best setup, but I find very
difficult  to use  biblio-koha-indexdefs.xml.

To test it in a english MARC21 setup:

Insert same records with titles and correct values in ind2 of 245.
If you have articles not in the skiping list of sort-string-utf.chr (The|the|a|A|an|An)
you can see that the sort by articles use also articles.

Insert the patch
Rebuilt indexes from scratch

Now all articles of titles are skipped

TO TEST WITHOUT INDEXING:

1. Go to etc/zebradb/marc_defs/marc21/biblios directory.

2. Put the sample MARCXML file in this directory.

3. Transform the file into Zebra indexes:
   xsltproc biblio-zebra-indexdefs.xsl record.xml
   Observe that the Title:s index contains:
   01 Business and Technologies

4. Apply the patch.

5. Repeat:
   xsltproc biblio-zebra-indexdefs.xsl record.xml
   Observe that the Title:s index contains:
   Business and Technologies

Verified working using yaz-client (as in
http://wiki.koha-community.org/wiki/Understanding_Zebra_indexing#Examine_Zebra_index,
though note that the `elem zebra::index` seems to be unneeded).
