Remove difficulty icon and name on the beatmap queue list when on freestyle multi

[pigeonskew]

Currently, what's listed is the specific difficulty of the map the players picked, just like before. But on freestyle, it's a different story. While you can argue that it doesn't matter in the end, I still think removing the difficulty icon and name makes things looking more sensible from a UI standpoint. I also don't think it's necessary for anyone in the lobby to know what diff the other players picked since.... who cares? That'll only matter when it's not freestyle.

Since everyone can pick a difficulty of the map that they want, I don't see this being necessary. It's just pointless.
Just leave the song title, artist and mapper.
