hidden skill rating

[.Memories.]

I think it's mostly okay, but a few changes might help.

1. Matchmaking should match top players better.
2. The time limit for removing inactives should be shorter. Or should only be reset by playing in that particular league. I.e., if I make it to #20 1v1, but then only play 2v2 for a year, I shouldn't remain on the 1v1 list.

Idk... wishful thinking. I'm sure there are better ways for everything that we haven't even thought about.
