CrashKill/Plan/User Notifications

This project handles a user notification system that both tells users about crashes they have encountered and we know something about as well as how to help themselves with malware we know and have detected to be loaded into their Firefox process.

The system needs multiple teams to be pulled in and has a longer term focus, we still need to come up with a plan for it.

See also PostCrash, which this project might overlap slightly.
