request: major improvement over the "report" system required

[Tran-Antoine]

As the title suggests, the current GameRoundReport system is terrible. Since it only allows the server to access a list of "raw" strings with no further indication, it is complicated to process this information and use it in a more advanced manner than just "print the raw strings". As a minor improvement, I already added a list of standings in the report that can be more easily manipulated, but the PollRound for instance does not yet have a solution for effectively retrieving the different couples player-answer

This had been slightly improved because we now also provide a leaderboard of standings with the report, but there is still a lot of work to do on that
