Match History: Add our mastery grades!

for unknown (as of yet) reasons, i often get disconnected in place of the end of game animations. the subsequent sequence of events leads to me missing the post-game screen. i can live without telling everyone in the lobby "gg," but i LOVE the grades from the mastery feature, and if i accidentally skip the post-game lobby, i don't get to see my grade! so i think it'd be GREAT if we could see our mastery grades in our match history, in addition to any ip/exp gain.
