Notify users that "pep8" was renamed to "pycodestyle"

[Ede123]

There are many places were there is still outdated information refering to "pep8" instead of "pycodestyle" making no mention of the name change (#466, #481) which can be quite misleading.

For example I just installed "pep8" unaware of the fact and wondered why it was outputting a lot of W503s when it shouldn't. That's when I realized the project had been renamed and I had installed the outdated pep8 version 1.7.0 instead of the current pycodestyle 2.0.0

I'm not familiar with PyPI and don't know if there is a possibility to deprecate packages but it would be a huge help for new users if the name change was announced prominently at [1] and [2].
An updated package of pep8 with a deprecation warning might be yet another option if that's not too much to ask.

13 months later and I've only just noticed the name change and am still on the old pep8 1.7.0. I've updated (or tried to update) pep8 many times, and a warning would have helped me.

A prominent note has been added to [2]:

Note

This package used to be called pep8 but was renamed to pycodestyle to reduce confusion. Further discussion can be found in the issue where Guido requested this change, or in the lightning talk at PyCon 2016 by @IanLee1521: slides video.

Thanks!

It'd be great to also put one at [1] as well.

I've created PR #690 to issue a warning in pep8.

On further investigation, it looks like the warning has already been done in d4a6003 in in May 2016 in the release/1.7.x branch, but not yet released.

Please could we have a new release of pep8 with that warning? Thank you!

Thanks! I think this issue can be closed now.
