The following methods have been implemented for supporting
content-type translations:
- H5PEditorAjaxInterface.getTranslations. This method is used for

the specific fields and messages for each content-type library.
- H5peditorStorage.getAvailableLanguages. This method is used to
get the language list displayed into the "Text overrides and
translations" section.
