rename package and PyPI package to pynvim

[bfredl]

And add dummy transition package.

[mhinz]

What's the rationale behind this change? I guess it's because we generally want to call it nvim instead of neovim?

Isn't the py superfluous?

No. The point is py- allows us to use the same name regardless of "it being a python package" is an implied context or not. There are lots of precedents for python packages with "py" such as numpy/scipy etc.

Right now, the same software is called python-client in neovim contexts, and neovim in python contexts. I've heard several reports on gitter "pip install neovim" being confusing for newcomers, as it looks like they install neovim twice.

Renamed some more things in 22e5919 .

• Should the non-transitional setup.py also be updated?
• scrutinizer seems confused, maybe someone can go to https://scrutinizer-ci.com/g/neovim/python-client/settings and use the "Rename" section. I don't have access there.
