Feedfetcher/HTTPClient fix

This fixes a typo which made the new Feedparser not use our own HTTPClient.
It also enhances the get() method of HTTPClient to optionally cope better
with bad HTTP responses:

Some servers return a body with a "304 Not Modified" status which violates
RFC 2616 but is usually accepted by common browsers. Setting the $sloppy304
parameter will return the response body. This fixes problems with feeds
from feedblendr.com
