Not enough crazyhouse tourneys

[isaacl]

Crazyhouse tourneys used to be every hour. But now, the hourly schedule only puts crazyhouse once every three hours, rotating with chess960 and koth, which are not similar variants. In practice, the hourly zh also sometimes gets usurped and not scheduled.

In contrast, antichess and atomic, much less popular variants, are scheduled in alternating hourly tourneys.

I suggest alternating zh and atomic, or returning to the hourly zh schedule. Happy to PR

Looking more closely at schedule, perhaps swapping antichess and zh hourly -- will decrease antichess freq and incr zh freq

Separately, I also think Atomic 5 0 should be made less common, as atomic tends have more forced moves and shorter games
