Reformat i18n correctly (#2976)

* Ignore i18n gen.dir key

* Add a makefile target to update an i18n key

* Mark some i18n keys to ignore

* Reformat i18n files correctly

* Make i18n keys sort case-sensitive

Calling `make i18n-format` was always inverting 4 lines:

- gen.date.dec with gen.date.Dec
- and gen.date.nov with gen.date.Nov

I don't know why these particular lines and not the others, but it
appeared the sort function was case insensitive due to the
`SORT_FLAG_CASE` flag passed to the `ksort` function. Removing this flag
makes the calls to the formatter idempotent and more reliable.

Unfortunately it moves a lot of lines since the `_` character is
considered differently.

* Check i18n files are correctly formatted on Travis
