PyPI urls point at launchpad

[Ivoz]

on PyPI, the Home Page and Bug Tracker references point at launchpad which was rather confusing since it was last modified in 2013.

Neither do the docs mention any information about contact, development, issues or contributing for the project. I had to guess that it was now hosted on Github.

It would be great if those links could be updated, and maybe a page in the docs could mention a small amount of info for contacting / helping the project, etc.

Maybe even the launchpad page could point a link/some links to the new development location as well.
