Subject: [PATCH] Bug 3216 Add CHR/ICU Zebra tokenization choice to
 installation

Word search with multi-part facets works properly only with Zebra ICU
tokenization. This patch add a new question to Koha command line
installer:

  Zebra has two methods to perform records tokenization
  and characters normalization: CHR and ICU. ICU is
  recommended for catalogs containing non-Latin
  characters. (chr, icu) [chr]

How to test:

  - perl ./Makefile.PL
  - Try each possible value for new parameter
  - Take a look at zebradb/etc/default.idx file.
    Depending of the parameter you get this line:
      icuchain words-icu.xml
    or this one:
      charmap word-phrase-utf.chr
