Title: Allowing nil content-type with UnsupportedContentHandler

* Some websites will not send a Content-Type header when the content is sent using 'Content-Disposition: "attachment"; filename=""'. Mint.com is one example of this, when downloading transactions to a .csv file. This patch fixes this problem, and logs a warning if this ever occurs.
