Enable the CDN for prod.

Clean up some settings for dev and prod.
Update bart to deal with shared logs on dev and prod.

Proposal:

* Dev will run `bart_dev.sh` on cron every minute.
* Prod will run `bart.sh` on cron every minute.

Prod receives logs, processes them, and moves them to the NFS. Dev then
grabs the newest one, processes it, then gzips it so that it won't do it
again.
