This allows the QFile factory there to actually return the payload in a unique_ptr instead of falling back to a raw pointer. The use of a unique_ptr member requires that the destructor be out-of-line, since QFile is only forward-declared in the header file. This is good hygiene, so do it for ProgressDialog, too.
