Notifications should disable packages that throw "too many" unhandled exceptions

Related to #103

Capturing errors is expensive. Some packages get into a bad state and start throwing more than the system can handle, bogging down the application. The notifications package should include some code that keeps track of unhandled exceptions and disables misbehaving packages. We could start with more than 1 exception per minute for 5 minutes or longer and tweak from there.

Rather than disable, can we just deactivate?

That's a possibility too. I didn't think too deeply on this, I just wanted to capture it 😀

Disabling is just a huge penalty to apply to a package author. It means that - should they release an update with a fix - it would still require manual user interaction to re-enable the package.
