Add some kill ratio and win percentage, clean up recent games.

Added the kill ratio and win percentage to the first section along with a breakdown of how I got them. Also cleaned up the recent games section so it looks more like what is on all of the other "leaderboard" pages, which people should expect. I removed the overall stats section altogether, as 99% of the time people are looking after what is currently provided (e.g. flag carrier kills = rather unimportant in the grand scheme of things).
