Problem & proposed solution

Commons Mass Description is a tool that can be used for adding descriptions to a lot of images on Wikimedia Commons at once.

On several places of the tool the internal API returns some kind of error (1, 2 and similar) and on the same time, returns HTTP 200 Ok as its status code. It'll be nice if Commons Mass Description could send HTTP 400 Bad Request.

Also, return JSON and 400 Bad Request on this legacy error raising.
