[refactoring] reduce nested scopes in handleDirectoryChanged() II
[notification] use "terminated" instead of "crashed" for processes shut down from quick-feedback

We use SIGQUIT to distinguish such crash reports.
[daemon] don't autodelete reports from user-terminated processes
[daemon] don't include user terminated processes into crash count
