Added Multi-Lang support.

[diego-feito-stori]

I made a fork to allow adding languages to the app, especially because some Chinese companies use it in Latin America and the USA, but the collaborators don't understand the language of the app, so I added the multi-language support and added ENG and SPA to my fork, and the community will have some benefice of it.

Please, if you have some time, give me some feedback. check #3115
