Fix the Getting Started guide for the new setup.py

With the new setup.py script, OpenStack must be installed before heat,
otherwise PIP will start importing bogus dependencies (at least on Fedora).

Also install stuff that was previously being installed by setup.py. This
will eventually be replaced with an install script (see #134).
