If a skin style explicitly does not include an icon in it's group order, no icon should be displayed.

I had some code in SlimBrowser to display radio icons in certain contexts, but it kills the UI elsewhere.

this is the SlimBrowser lua code I'm commenting out. It's possible my elseif could be modified to target only the item I'm looking for, but really the skin should not barf out icons if they aren't desired in that style.

 elseif item["params"] and item["params"]["track_id"] then
                if menuAccel and not _server:artworkThumbCached(item["params"]["track_id"], 56) then
                        -- Don't load artwork while accelerated
                        _server:cancelArtwork(icon)
                else
                        -- workaround: this needs to be png not gd because in gd it looks like garbage
                        _server:fetchArtworkThumb(item["params"]["track_id"], icon, _artworkThumbUri, 56, 'png')
                end
