src/Tweeper.php: add a retry mechanism for cURL sessions

Sometimes the connection to a remote host may stall and a resource
cannot be retrieved. This makes Tweeper hang for a very long time which
can be annoying for users.

Setting a shorter timeout and a retry mechanism usually works around the
problem allowing the resource to be retrieved eventually.

Implement such a mechanism by adding curlExec() method and while at it
move non-curl related messages outside of getUrlContents() and
getUrlInfo() to give the user a better understanding of what actually
failed when even the retry mechanism was not able to retrieve the
resource.

Add option to enable or disable showing usernames in RSS items

Tweeper shows usernames by default in items created from multi-user
sites like Twitter or Instagram.

This is because  the main use case is to aggregate multiple feeds in the
same viewer, and in this scenario having some info about where the
messages is coming from can be useful.

However sometimes tweeper can be used to track one single feed and in
this case having always the same username repeated over and over is
unnecessary.

Make showing the username optional, but keep the current behavior as
default.

NOTE: for Twitter keep always showing the username in case of retweets
($screen-name != $user-name).

This allows binary attachment without a more specific content type to be

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"

< 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.
