[Feature] Add support for localization

[IvanMazzoli]

Is your feature request related to a problem? Please describe.
English is for sure one of the most spoken languages around the world, but adding localization support for multiple languages would be a nice feature.
There are already a ton of strings in the project and starting now will ease the addition and translation of new strings in the next updates.

Describe the solution you'd like
Export all the hardcoded (are they?) strings in an XML/other type of file or use an online tool like Crowdin to allow contributors to add their native language to the project. Every user should be also allowed to choose their preferred language. If a string is not translated, it should fall back to the english one.

Describe alternatives you've considered
A good english course for the ones who doesn't speak it!

Additional context
I would be happy to help with the Italian translation for the project, as I recently did for EmulatorJS.

it pulls the descriptions and data in english - not as bad, but having it in other languages , spanish, german ... etc would be nice to setup
