Track crew clone count

[whoabuddy]

We should track how many times a crew is cloned, and use that as a possible way to sort on the public crew page.

We could also introduce a star feature like GH, so you can sort by "most starred", but feels like an extra step vs just capturing how many times it was cloned.

Sounds like another good usecase for sorted-set/leaderboard data structure.

We don't have clone crew now😃
