Italian, French, and Portuguese!

Repetium now supports 🇮🇹 Italian, 🇫🇷 French, and 🇵🇹 Portuguese!

Initially, the supported languages were 🇬🇧 English, 🇩🇪 German, and 🇪🇸 Spanish.

What remains to be tackled: variants of languages. For now, languages use their international variants. The plan is to account for local variants, such as Brazilian vs European Portuguese, or Argentine Spanish vs Castilian Spanish, and so on.

For now, the focus lies on improving the application with the base (international) versions of supported languages.
