Bug 27153: Adjust mappings to add title without punctuation

This patch finally adjust the default mappings to add a new field to
the elastic index with the title stripped of punctuation

This method optionally allows the library to place the filtered version in the
same
search field, or a new search field. The default mappings will include the
filtered version
in a keyword search, but not a targeted search

To test:
1 - Import some affected records via z3950, e.g.:
    Carrie's war
    1,000 Japanese words
2 - Search (using Elasticsearch) for the titles without including punctuation
    Carries war
    1000 Japanese words
3 - No results
4 - Reload mappings and reindex
    perl misc/search_tools/rebuild_elasticsearch.pl -v -r
5 - Search again
6 - Success!
7 - Search title specifically:
    ti:Carries war
8 - No results
9 - Adjust mappings.yaml to add second mapping for 245 to title index:
    - facet: ''
      marc_field: 245abp
      marc_type: marc21
      sort: 1
      suggestible: 1
      filter: punctuation
10 - Reload mappings and reindex
11 - Repeat 7
12 - Success
