Version 2.4.1: Italian and Spanish translation

The version 2.4.1. adds Italian and Spanish translation to Cantara. Despite that, there is no additional functionality compared to Version 2.4.0 which means that if you are not using one of the languages, you don't necessarily need to update to this version.

Thank you to the translators!
