Add all files in i18n folder to npm repository

I belive it was unremoved stub, because in the current version of .npmignore file there is no restrictions for these files.

This has not the intended effect. Now only the following files are distributed:

• ej.culture.ar-AE.js
• ej.culture.de-DE.js
• ej.culture.en-US.js
• ej.culture.es-ES.js
• ej.culture.fr-FR.js
• ej.culture.vi-VN.js
• ej.culture.zh-CN.js
