Title: Allow downloading of original uploaded file from box.

Per the Box View documentation:

> GET /documents/{id}/content.{extension}

> Fetches a document in the form specified by extension, which can be one of pdf or zip. If an extension is not specified, the document’s original format is returned.

Also fixes Bug #6
