src/Tweeper.php: use a minimal User-Agent string to fix scraping twitter.com
Twitter.com has started serving the user timeline via json when the user
agent is a modern browser, this breaks scraping in Tweeper which expects
html content.
Remove any version info from the User-Agent header used by Tweeper to
make twitter.com think it is talking with a very old browser, tricking
it into serving html content.
NOTE: Tweeper cannot just use the default User-Agent from the CURL
library because this would break scraping Facebook.com; using a minimal
but still browser-like User-Agent seems to be a viable common
denominator for all sites currently supported by Tweeper.

Fix information leakage by validating the URL scheme
Validate the scheme to prevent leaking information by abusing the
file:// scheme.
Before this change it was possible to see what files are available on
the system running tweeper.
The script in tests/test_information_leakage.sh shows the problem on
earlier versions.
Here is an execution with tweeper-0.6:
-----------------------------------------------------------------------
URL file://twitter.com//etc/passwd
--> /etc/passwd
exists
URL file://twitter.com//etc/file_with_an_unlikely_name
... /etc/file_with_an_unlikely_name
does not exist
Staring a test server
URL file://twitter.com//etc/passwd
--> /etc/passwd on http://localhost:8000
exists
URL file://twitter.com//etc/file_with_an_unlikely_name
... /etc/file_with_an_unlikely_name on http://localhost:8000
does not exist
Shutting down the test server
-----------------------------------------------------------------------
Here is an execution after this fix:
-----------------------------------------------------------------------
PHP Fatal error: unsupported scheme: file in /home/ao2/Proj/Tweeper/tweeper/tweeper.php on line 323
URL file://twitter.com//etc/passwd

tweeper.php: check the return value of Tweeper::tweep()
If the tweep() method fails return 1 to the calling process so that it
can know that something failed.

tweeper.php: check curl_exec() return value
Also show the message of curl_error() when curl_exec() fails, this way
it's easier to diagnose problems.

tweeper.php: support "application/pdf" as an enclosure content type

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"
< Last-Modified: Sun, 11 Sep 2016 22:01:22 GMT
< Accept-Ranges: bytes
< Content-Length:
14346711
< 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.

tweeper.php: fix a problem with https URLs ending up in the enclosure element
When the remote host forces every URLs to be redirected to https, the
info returned by Tweeper::getUrlInfo() would contain an https URL, which
will end up being used in the "url" attribute of the enclosure element,
and this is invalid according to the RSS specification.
So make sure that an http URL is actually used for the "url" attribute.

Use php:functionString() in the stylesheets where appropriate
Instead of converting to string in XSL and then calling php:function(),
use directly php:functionString() when calling PHP functions which
actually expect a string argument.
Besides possible performance improvements, this is done mainly for
readability.

Don't convert the timestamp to a number when calling php:functionString()
It's not needed to convert the $timestamp variable to a number before
passing it as an argument to php:functionString() as the latter will
convert it to a string anyways.
