Implement sharding counter scheme for computing the total donations. #40

Closed hjfreyer closed 10 years ago

This change increments the counters, and stores all the pledges with model_version=2 for tracking. We don't actually use the counters yet. Once this is live and no more pledges are coming in without model_version>=2, we'll count the total donations for pledges not included in the counters, and manually add that.

Yeah, very nice. I love that it uses a task queue too.
