NetzGrafik-Editor (NGE) translation

[louisgreiner]

Description

This issue is a direct contribution to NGE front-end official repository.

i18n interface already exists in NGE for German / English (default) / French / Italian, but is empty. The purpose of this issue is set the i18n attribute on the right front-end elements, and to fill the static translation tables.

We aim to improve the quality of the app by refactoring the .xlf translation tables to .json.
