Cloudflare now also checks the client's SSL/TLS cipher capabilities and
produces a 403: Forbidden response with CAPTCHA if they are insufficient.
This commit replaces the default cipher list in urllib3 < 1.25 with the
one from 1.25 (1), which doesn't cause problems as long as the client
platform actually supports these ciphers. On some platforms (tested with
Python 3.4 on Linux and Python 3.7 on an outdated Windows 7 VM) it is
necessary to install pyOpenSSL to get everything to work.
Explicitly setting a minimum/maximum version for urllib3 is also no
longer necessary and installing gallery-dl will therefore not pull a
incompatible urllib3 version (#229)
Fixes the "403: Forbidden" error on Artstation (#227)

Wouldn't be necessary if pip would do proper version management.
As things are right now, pip ignores the urllib3 version requirements
from requests because gallery-dl is specifying its own.
urllib3 versions 1.24.1 and 1.24.2 cause HTTP requests to
https://www.artstation.com/users/<username>/quick.json
to fail with a 403: Forbidden status code (#227),
and provoke a CAPTCHA response after solving a Cloudflare challenge.
- uses an OrderedDict for session.headers (since 2.9.2)
- ships with urllib3 1.16, which is the first version to have an
'allowed_gai_family()' function
