New features how switch language to portguese and more

A fully responsive page with a slightly modified layout. All challenge functionalities were implemented, but new features like 'Loaded Countries' and 'Language Switch to Portuguese' were also included.

I'm very happy with the outcome, but not so happy with the code... I haven't had time to refactor it yet. Since I'm not very familiar with React yet, I decided to do this project using only HTML, CSS, and JavaScript... React was sorely missed on MANY occasions.
