[directory-upload] Should Directory be cloneable? (#27)

Scenario:

* User drag-drops a directory onto a page
* Page wants to delegate to its controlling Service Worker, so uses `postMessage()`

This could be done by traversing the directory structure, minting paths, and posting an array of (path, File) pairs, but if we're introducing a Directory primitive it seems like it should be cloneable.
