- There's no need for configuring "trans.<lang>" for each resource.
Using the global "lang_map" in the Transifex client config is enough.
- The Transifex client can rename locales. No need to do this manually.
- Pull all translation files for each locale that has a file named
config/locales/client.<lang>.yml. Up until now the script did only
update existing files, but didn't add missing ones. That is why there
are so many translation files for the poll plugin missing.
