It might be worth pinging Jim Coble at Duke to see when he plans to finish work on porting proxies/transfers over to Sufia.  If that is soon, I think you can remove this file from this PR.  If it's not gonna be a while, we should probably leave it here *and* put in a Redmine ticket to the tune of, "remove dashboard override and proxy/transfer functionality from ScholarSphere when feature is ported to Sufia"?
