DnD components without versions

When the user DnDs a list (e.g., package json) or another version ambiguous source of components, ClearlyDefined should do its best to pick smart defaults (e.g., latest) for the component.

Note that this may involve doing some "lite" version resolution based on the notation of the component type (e.g., drop a package.json and the npm version ranges are honored and the latest in that range is added to the list)
