#10 Folders that don't exist anymore should just be removed

[Anonymous]

On startup, the WF app checks to make sure that all watched folders still have their WF contents. If they don't, a dialog appears asking if the files should be replaced or the folder dropped from the watch list.

When the folder doesn't exist at all anymore, the dialog still appears. Assumably, clicking "repair" will cause a crash. The dialog should not appear if the entire folder no longer exists; the folder should just be silently removed from the watch list.
