Update uclouvain-centre-charles-de-visscher-pour-le-droit-internation… (JabRef#4871)

These changes were made by a student after he received feedback from a group who used this style. He then submitted this updated version of the style to me. It's been so long since I worked on this code, I'd be very happy if someone could help me and see if everything seems OK.
