[directory-upload] The spec should define integration with FormData (#14)

The spec should define how Directory objects interact with [FormData] (https://xhr.spec.whatwg.org/#interface-formdata). Things like what happens when a Directory object is passed to the append() method. Note also that currently the text over there says about the filename field "its filename is the value of entry's value's name attribute", which ignores the 'path' data that the Directory Upload text currently says should be included in the filename field.
