Comment 1 for bug 715617

Added new constructor parameter to LuceneSerializer:

public LuceneSerializer(boolean lowerCase, boolean splitTerms, Locale sortLocale)

which is used in sort field generation:

sorts.add(new SortField(toField(path), sortLocale, reverse));

In the future we might want to add support to set sort locale per field, but I think it can wait until a real use case emerges.
