Bug 10729: Add phrases configuration for ICU

Bug 10729: Add phrases configuration for ICU

Add a separate phrases-icu.xml for phrase indexes
The file is based on that distributed with zebra
with a couple of additions to reflect Koha usage

This patch adds a separate tokenizer variable
for phrase indexes so that default.idx is
correctly rewritten for sites using icu
indexing
