Simple Django model translations without nasty hacks.
copied from cf-staging / django-parlerFeatures: - Nice admin integration - Access translated attributes like regular attributes. - Automatic fallback to the default language. - Separate table for translated fields, compatible with django-hvad. - Plays nice with others, compatible with django-polymorphic, django-mptt and such: - No ORM query hacks. - Easy to combine with custom Manager or QuerySet classes. - Easy to construct the translations model manually when needed.
