Remove ``border-left`` in playerlist

Pre and Post screenshot below.

Reason:
Since the ping feature is not in use, this is a relict for now.

Currently it looks kinda off to me as it is "blocky" (i.e. a gap between every user) since there's no difference in color.

Smol change, huge looks

@final fog could we use the border to display something useful? maybe green means no kick no warns no bans, yellow means warned and red means has been banned or kicked before? maybe something useful

I like the sound of that.

yes that's the idea
