django/setup.py
Carl Meyer 6ed7d40727 Fixed #18115 - added warning about overlaid install.
Setup.py now warns if it detects that Django is being installed over top
of a previous installation that was never removed. This should only
happen when installing with ``python setup.py install``, as pip
automatically uninstalls before installing a new version and
easy_install installs as an egg directory.

Also generally updated the installation doc.
