Title: Declare dependency on ext/intl

Composer's error messages are confusing if the `intl` extension is not present on a system, and upcoming extension installers (think Pickle integration etc) or other means (my use case: auto-enable intl on Heroku if a dependency needs it) can enable the extension without having to alias "lib-icu" to "ext-intl" somehow.
