[FEATURE] Internationalisation

[Shaquu]

According to this page internationalisation is supported in node-red modules.

So after I add English locale there will be a change for more people to contribute using their translation skills.
I assume we will have at least 3 languages for now:

• english
• german
• polish

Landed on feature/i18n

@ptath @radokristof this PR is experimental but it's not much work to do here so I would be happy to see more languages 👍
