Add support for Python 3.8

[Legrandin]

Python 3.8 was released on October 14th, 2019.

Can it be added to cibuildwheel?

[YannickJadoul]

Yessss, thanks for the reminder! Should be reasonably quick to implement, though it depends a bit on the Python versions AppVeyor and Azure are offering.

@Legrandin, see #172 to follow progress :)

So far, it seems that Azure Pipelines and AppVeyor do not support Python 3.8 on Windows, yet.

Fixed in #180. Release should be within the next couple weeks...!

Are there any news on when to release it?

@MuellerSeb In the meanwhile, pip install git+https://github.com/joerick/cibuildwheel.git should work, though?

Since I want to use it in CI, I'll wait for the next official release, to stick to one version.

I want to be sure that #175 isn't a problem and merge #169 before release... so I can't give an exact date, but within a couple weeks :)

[MuellerSeb]

I'm cool with that. Thanks for your great work!

@joerick In principle, the docs don't need to be ready before release, right? Commits to README on the master will show up immediately on GitHub, and the readthedocs can build independently of a release?
