Add Point Gain/Loss Info to MM Match Summary Pages

[Satamari]

It would be quite neat to have the MM summary page (example) show how many points each player gained or lost from that specific match.
As I understand it, the point deltas for each player are already being calculated by TMio (as shown in the individual player match histories, so linking them to the corresponding players via the match-ID should hopefully be somewhat doable.

For reference, this would require fetching each player's match history (at that point in time, but I guess we don't have to go back more than a month since Nadeo doesn't store matches for longer) to calculate their delta for this match (meaning we can only display it once the match has been recorded in Jonese's API, which can take a few minutes after the match is finished).
