Make file system scan more robust 

Previously, a change was missed if it happened while the scan was in progress and already past the affected location.

Also:
- Consider the scan changes thread on termination, in addition to the full scan one
- Add FS-reported hidden to the check for hidden by the editor file system

(cherry picked from commit 3017bdb7ce)
