Add multiplayer scores sorting

bancho.js should be able to sort the scores of each player at the end of the map, just like Bancho/the osu! client does.

If in TeamVS, rankings should be made by teams and sum of their players scores (fails count for 0).

If in 1v1 scenario, rankings should be sorted first by pass/fail, then by score.

I'm not really sure what the data structure of all of that would be, discussion is open for that.
