[sugar] Viewing PDFs from Browse

The user couldn't annotate a file they don't "have".  Obviously we
have to download the bits to a temporary location to view them, but in
the normal paradigm of the web, nothing is permanently kept unless you
explicitly download it.  Perhaps an attempt to navigate away from the
page could ask if you wanted to keep it around or not, but I'd just as
soon expose the keep button and have kids learn to keep only what they
actually want.  Everything on the web is transient unless you grab
something while you can.

It doesn't really make sense to me to add annotation tools and such to
the pdf viewer in Browse for this reason.  It should remain limited to
handy viewing controls, saving the annotation tools for Read once the
document is local, I feel. (As an analogy, you wouldn't expect to be
able draw on top of or otherwise edit an image within Browse, right?
You'd be able to zoom, pan, *maybe* rotate; but you'd download it and
edit it in an activity designed for that purpose.)
