Resolves#205 - pypi.python.org shutting down
* Updated the default fallback URL to `pypi.org/simple` rather than
`pypi.python.org/simple`
* Scrubbed references and links to `pypi.python.org`
* Fixed tests breaking due to the removal of `pip.main()` in pip 10.0 -
see pypa/pip#5080 for more info
Resolves#179
Due to a pypi API change (reasoning
[here](https://mail.python.org/pipermail/distutils-sig/2017-October/031712.html),
thanks to @natefoo for the link), the redirect links that we were
generating for distributions not present in the package index were
failing with `403` errors.
@ankostis, I have not had time to look into why the standalone tests are
failing. Perhaps we should just ignore them in order to get a new
version out once this is merged to master?
* Updated .travis.yml to fix PEP 440 warnings
* Fixed twine calls
We were getting test failures on multiple branches in
`test_server.py`. I first investigated a warning message
popping up in every test run:
```
PEP440Warning,
/home/travis/virtualenv/python3.5.2/lib/python3.5/site-packages/pkg_resources/__init__.py:2510: PEP440Warning: 'setuptools (git-0.4.0)' is being parsed as a legacy, non PEP 440, version. You may find odd behavior and sort order. In particular it will be sorted as less than 0.0. It is recommend to migrate to PEP 440 compatible versions.
```
Moving the installation of setuptools, pip, sphinx, and tox
into the `install` key for Travis resolved that issue, but
`test_server.py` tests were still failing. It turns out that
Twine 1.7.0 added support for SSL cert specification and,
in the process, changed the call signature for the `upload`
and `register` internal methods.
This PR fixes the calls so that they align with Twine's new
function signature. Note that tests now fail on Twine <1.7.0,
so I have also updated the dev requirements file.
