- Fixed an error in the spanish and chinese translation file
- Refactored reading the translation files
Instead of ignoring errors in the non-default language files
the error will now be returned and the remaining files will
not be loaded.
- Added a unit test to check if all translation files are valid
- Added an i18n config to specify the translations dir and the
default language
