feat(xanthous): Store language on creatures r/2659
Add a new "language" field to the CreatureType raw type, which
references the *name* of the language that creature speaks (this is so
that different creatures can speak the same language without having to
duplicate the language definition in the raws). At some point this
should change to not hardcode the sets of languages and instead define
them in data files like we do for creatures, but this is fine as a
start.
