Generate package list automatically in find_packages

Previously, the package list was manually specified, which meant that
it became out of date any time a package was added, and IPython would
become uninstallable. This would not be noticed for some time by
developers, who always use `setupegg.py --develop` or symlinks.

This update immediately revealed that IPython.zmq.tests and IPython.extensions.tests were never included in 0.11.  Other than that, there is no difference in the package list.
