Git commit f70b9905f5d7b31563452970c5cbae9995dbdbfd by Boudewijn Rempt.
Committed on 28/02/2017 at 14:24.
Pushed by rempt into branch 'krita/3.1'.

QFileSystemWatcher cannot be deleted in a different thread from
where it was created. That did happen when a file layer was deleted
after converting it to a paint layer when the undo command was
pushed off the stack.

This change creates a single static QFileSystemWatcher that all
file layers connect to. fileChanged checks that the changed file
is the right one before setting the fileChanged flag.
