The canonical Pipenv documentation is now at pipenv.pypa.io.
Also, the canonical GitHub repositories for Pipenv and
Requests have changed, and some other communications links
(Twitter, mailing list, "thank you") were no longer
operational. This commit updates those and clarifies that
Pipenv is a project maintained by the PyPA.
Fixes#4137.

Removed ppa mentions from documentation, and re-organised the page a bit
to make it structurally easier to upderstand.
Both the documentation's front page and README.rst now actively refer to
the page so user can be directed to better installation methods. (I
don't think this is very useful TBT because people don't use manuals,
but we should still do it.)
Also fixed many Sphinx warnings during documentation builds.
