Decrease TurfWar background query intervals

Browse source 
The database is much larger than it was when we started, so these
background reporting queries have become much more expensive than
before. We also had someone make 750k claims in one day, and even
hundreds of thousands per hour, which broke our assumptions about
hourly / daily reports being cheap.
