we still need to call a text/html downloaded from a google docs
'document:blah' document id a .doc, since the assignment may be
restricting submissions to '.doc'. however, we don't want to claim that
said document is scribdable, because it's not. fix already uploaded docs
that were scribd when they shouldn't have been.
be smarter about inferring extensions for google docs downloads while
we're at it.
