tweeper.php: support "application/octet-stream" as an enclosure content type
This allows binary attachment without a more specific content type to be
supported for the enclosure element.
Adding "application/octet-stream" also covers the weird case of servers
sending multiple Content-Type headers, e.g.:
< HTTP/1.1 200 OK
< Server: Apache
< ETag: "
a46d495ba00c35580f83344dd523ece2:
1473631283"

< Accept-Ranges: bytes
< Content-Length:

< Content-Type: audio/mpeg
< Content-Type: application/octet-stream
< content-disposition: attachment
< Date: Mon, 26 Sep 2016 23:36:11 GMT
< Connection: keep-alive
< Content-Type: application/octet-stream
< content-disposition: attachment
In this case the ideal solution would be to use the more _specific_
content type, but CURL just remembers the _last_ one ad it's not really
worth parsing the HTTP headers in tweeper just for this rare scenario.

count, likes count) to present at least something.

rss_converter_twitter.com.xsl: update XPath of tweet content
Using the role attribute to differentiate between original tweets and
quoted tweet, as introduced in commit 4c2e986, does not work anymore,
but the fact that original tweets are <li></li> elements while quoted
tweets are <div></div> elements can be used instead.

rss_converter_twitter.com.xsl: restrict tweet matching
With new style retweets the quoted text is also matched by
[@data-item-type='tweet'] but then the content is not handled, resulting
in empty items in the RSS feed.
Checking also for @role='listitem' allows to pick up only top-level
tweets.
