Translate month names into the user's locale

This has been mostly done with changes in the datetime crate's suddenly
supporting locales.

It's still important that the user's locale is touched only once and
cached from that point on, so a struct in output::details has been made
public, along with that module. This will change later as that object
gains more and more uses thoughout the codes.
