UHC Event Stats + leaderboards fixes

[pasriram04]

I got multiple suggestions for UHC here:

1. In UHC, Event Modes Solo Brawl and Duo Brawl had their second iteration in mid 2020, and their stats aren't displayed on Plancke.io at all. So, kills and wins don't add up to the score. This should be fixed. In game too, some kills counted to score and some didn't, and since Plancke is an admin he could implement a fix to that.
2. The Red vs Blue event mode didn't give score and shouldn't be counted to the Overall stats.
3. For the UHC leaderboards, only Teams Stats are shown and the Top 1000 players by Teams Wins are displayed. This is unfair to solo main players like me. Instead, I suggest multiple leaderboards for UHC, one for Overall (sorted for score), and one for Solo and Teams (event modes may or may not be ignored) sorted by Wins. Thanks for reading!
