bug#15510: Make python.el work with IPython automatically

[Stefan Monnier]

Package: Emacs
Version: 24.3.50


I think python.el should try to automatically detect which kind of
interactive loop is running and use the corresponding invocation, so
users don't need to manually set python-shell-prompt-* and
python-shell-completion-* variables (and they can then even switch
between various interactive Python shells seamlessly).
