Olivier Meunier 887d0028d1 Moved locales to BCP47 codes ...

This is a big change, as it renames locale and documentation folders.

- renamed translation folders following BCP47 codes
- improved display of available translations
  Each translation is now displayed in its own language and in the
  current user's language.
- the default language is now "en" instead of "en-US"
- renamed folders in docs/src and docs/translations
- don't copy images from docs/src when they don't contain an index.md
  file
- added a user.Lang() method that returns a code that is guaranteed to
  be available in the locale list
