Add civilisation name and icon alongside the names in the top bar#95

Pretty self-explanatory. That section is where the eye is drawn to, and I think is where everyone expects that information to be, before realising it isn’t there and hunting for it. It’s bad enough that I’ve ended up making a custom/manually updated overlay just to slap something on top of that area and add it in myself… but if others don’t feel the same way, would be great as a setting you could toggle.

Adding the players’ flag would also be interesting as an optional feature.
