Improvement: Show the level of group members in listed groups

[HelgeBecker]

As the tile says. Show at least the current level of the group leader or offer to who him without the need to type his name.

If not feasible then provide a button to /who the player in your chat.

[DomenikIrrgang]

Not possible anymore after the recent update to do it automatically, might provide a button later down the road.
