Ported the IPython Sphinx directive to 0.11....

Ported the IPython Sphinx directive to 0.11. This was originally written by John Hunter for the 0.10 API, now it works with 0.11. We still need to automate its test suite, but at least now it runs and the script itself can be executed as a test that produces screen output and figures in a subdir.
