Expose ICU version on Special:Version

ICU (International Components for Unicode) <http://site.icu-project.org/>
is used to implement ordering of category members (category collation)
when $wgCategoryCollation is set to one of the supported "uca-xx" collations.
Its version determines whether the ordering will be correct for a number
of languages MediaWiki supports.
