add ipython and ipython-notebook packages to the build
the "mad genius" epifanio does fun things with ipython-notebook.. it makes a graphical environment and he uses it to plot science data and drive OSSIM. It is about 26M install and when it runs it takes port 8888. The spreadsheet says that nothing else uses 8888.
Hamish is concerned about using common ports numbers, but we allow 8000 and 8080 already!
