Make importing NetNewsWire 3 subscriptions a one-step process — use an accessory view in the NSOpenPanel. Also: refactor to use immutable structs instead of classes; use static methods on structs; reduce API surface; don’t flatten sub-folders (let the OPML importer handle the flattening, which it already does).
