More Arena Rating Info after Match

[Glitchless]

After an arena match, you will now see how your team's average rating compared to the enemy team's average rating for the purpose of rating gains/losses.

The winning team will see a message displaying the gap between both team's actual ratings. This is because rating gains are always based on each team's average actual rating.

The losing team will see a message displaying the gap between the other team's modified rating and their actual rating. The modified rating is whichever is higher: average actual rating or average individual (historical) ratings. This is because the amount the losing team loses is reduced if the players they fought have higher individual ratings than their current ratings.
