City and country as a must in affiliations

[marton-balazs-kovacs]

For most journals, city and country should be included in the affiliation. Based on the current layout of tenzing it would be quite hard to make this a requirement in the contributors' table. Maybe we can add checks or add tips and tricks info to the app so that users know what to look out for.

I think it is beyond the scope of this application to tell people how to fill their affiliation information. If we want to go this direction, a website/video instruction might be better than adding checks in the application itself. I am pretty sure what is required may depend on the publisher, too.
