Group contests based on online judge

[MohamedIrfanAM]

Enhancement #95 When sortBasedOnOnlineJudge config option is set to true, contests are sorted bases on the online Judges Example CodeforcesCodeforcesRound360Div.2 -> Codeforces/CodeforcesRound360Div.2 AtCoderAtCoderRegularContest167 -> AtCoder/AtCoderRegularContest167

From what I understand we are not sorting anything here, we are instead grouping right? So I would suggest to change the flag name to something more representative like: groupContestsByJudge or useJudgeFolders or anything else that represents this feature better

Thanks for this contribution and for the decision of adding it as an opt-in and not default behavior.

I agree groupContestsByJudge is more suitable name
