Add a couple tiny timing fixes for the lumina-fm backend:

1) Rollback the directory checked timestamp by 1/2 second from teh current time when doing a sync (just in case multiple fast changes to the dir).
2) Activate the dir watcher on all the files as well (not just the dir), and send all those signals into a collection timer with a 1/10 second delay to combine any simultaneous signals/changes into a single update call.
