Exception catching and reporting

Eclipse provides some sort of functionality for catching and reporting unexpected exceptions from plug-ins. That is, I've seen these reports for WTP.

We need to figure out what this is and determine if we can hook into this service so that we get these reports for our plug-ins.

Make sure we don't unintentionally collect PII, but a pure stack trace (no exception messages, no method arguments) should be safe.

- [ ] Decide on classes to allow unscrubbed (currently: `java.**`, `javax.**`, `sun.**`, `org.eclipse.**`, and `com.google.**`)
