More pleasing association detail rendering
- render both players with white background (instead the darker bluish gray)
- render both players with their topic icon. (Question: what to render for an association player?)
This way the rendering would be more consistent, e.g. with topic list rendering (detail panel)
- render entire detail background with the corresponding light tone (color palette) of the assoc color (e.g. the "Organization Involvement"'s green).
