This is one of the last extensions to be converted to having
the API messages in a separate file (at least out of the extensions
that are used be Wikimedia).
This one is a bit different from the others because it actually as several
extensions with separate i18n files, so it requires extra-careful review,
especially in Gruntfile and the extension.json files.
Bug: T189982

As pointed out by Umherirrender, this does not entirely work
for ConfirmEdit in this way, as there're several subdirectories
which also contain i18n files. I'm not sure why I missed this
in the first place, therefore reverting for now.
This reverts commit 24864a36bd.
