No notification when a dataset is copied

[alex-r-bigelow]

When a user makes changes to a dataset that they don't have write access to (e.g. they change the type coercion settings), the dataset is copied silently.

Need to fill in this stub (events may not necessarily be wired correctly).

@ronichoudhury, this may be a good one for you to start with when I'm gone, to get exposure to the mess that is the client-side code

Roger that. Thanks!
