Icon / different color for players you and your teammates killed

[lucasjoao]

I was seeing the project board looking for something that I could contribute. So I saw this card https://github.com/orgs/pubgsh/projects/1#card-10815648 and I think that I could work on it.

@apazzolini, what do you think?

Sure, thanks! I think a different color is preferable (and easier).
