[directory-upload] Consider how HTMLInputElement.getFilesAndDirectories could be used to avoid I/O blocking for FILE picking (#11)

Consider how getFilesAndDirectories could be used to avoid I/O blocking when a file (not directory) picker is used. By that I'm referring to the importance of setting .files to null, as described in issue #8. On way might be to add an 'async' attribute or some other means for authors to flag to the UA that they will use getFilesAndAttributes instead of .files and so would like earlier firing of the 'change' event.

We should consider this now since the mechanism that we choose may impact on the API for directory picking itself.
