Subject: [PATCH] Import system translations from official CI depot
 https://github.com/bcit-ci/codeigniter3-translations

Only files already existing in EA! were imported.

CI's portuguese-brazilian folder was used for EA!'s portuguese-br.
CI's simplified-chinese folder was used for EA!'s chinese folder.

No supported translations exists for Finish and Luxembourgish. The migration_lang files for these languages are still in English but one translation key is missing compared to the EA! English original file.
For consistency purpose, the Finish and Luxembourgish migration_lang files have been overwritten by the EA! English original file.
