Changed the way that the result from the webp test is stored to a more reliable one and the way that imports are made to a more correct one, since the last one had a big switch. It didn't improve in performance but I think this the correct way of doing it in a centered file.

Changed the way that images are loaded, now the browser will use webp when supported, saving data for more limited connections

Fixed responsiveness of some items in Editar Perfil page, links to request professor account, professor account form and other minnor things
