Subject: [PATCH] Generalize Reply impl for Box<dyn Reply> (#450)

We had a case where we were boxing up replies, and needed them to impl `Send + Sync` to use in other code. `Box<dyn Reply + Send + Sync>` unfortunately doesn't implement `Reply`, because the impl is too specific. This generalizes the impl of `Reply` to include any `Box<T>` where `T: Reply + ?Sized`.
