Levels for players already in challenge group

[Omnia0001]

Implement 'Inspect' button for challenge groups that would pull up the window of the challenge group ("Name level") - like the same window you can get when you join and hit the challenge group button on the side when not full. Seeing a different colored text (Lv X+) next to the name or in the inspect window is also relevant info for some people.

In terms of polish or more new content? I feel that a good mix help the best, having a patch or two of a couple of small polishes or one big polish then fielding a new content patch helps.
