This patch add zebra indexes to RDA 264 field.
The new Provider index is added too.
QA comments corrected.
To test:
1) Download RDA records with 264 fields from this attachment <http://bugs.koha-community.org/bugzilla3/attachment.cgi?id=36825>. Import the file and re-index/rebuild zebra. These records contain 260 and 264 fields per record.
2) Do a search with pb:Bethany two records will appear with title The guardian. Search with pl:Minneapolis too, the two records will appear.
3) Select one record of both records and delete the 260 field keeping the 264 field and save, rebuild your zebra.
4) Search again with pb:Bethany and just one record will appear. Thats mean 264 is not indexed.
5) Apply patches.
6) Rebuild your zebra but this time all biblio records.
7) Search again with pv:Bethany or Provider:Bethany, this time will appear the two records, 264 is indexed. Note that if you search again with pb only one record appear. This is because the suggestion of LOC.
