Implement the "download as" functionality properly in the iOS app
We need to catch the downloadas message already in
-[DocumentViewController
userContentController:didReceiveScriptMessage:] and use an
UIDocumentPickerViewController to let the user choose where to
download (or export) the document. The iOS-specific code in
ChildSession::downloadAs() can go away.
