Add project URLs to setup.py metadata for PyPI
This will make it easier to find e.g. the changelog or mailing-list by adding links to the left bar on the pypi.org page:
I thought that you linked from the README because you wanted people to be able to get there easily from the PyPI page. Right now the first link you find when scanning the README is a link to the PyPI page, you have to scroll two pages down to find the changelog and mailing-list. Apologies if I was wrong.
In fact, I got here by clicking on the "GitHub statistics" links that show up on the left, and then browsing back from the "stargazer" page back to the repo index. I suppose I could have checked whether the "Homepage" link was GitHub, but it often isn't, so that's what I usually do when there's no "source" link.
If you think this makes it too crowded, no worries, I just thought it would be helpful. I don't think you can prevent the whole "GitHub statistics" section from showing up though, as long as your "url" field points to GitHub.
