Fedora 21: 2015-14901 Critical Update for ipython XSS Issue

IPython provides a replacement for the interactive Python interpreter with

extra functionality.

Main features:

* Comprehensive object introspection.

* Input history, persistent across sessions.

* Caching of output results during a session with automatically generated

references.

* Readline based name completion.

* Extensible system of 'magic' commands for controlling the environment and

performing many tasks related either to IPython or the operating system.

* Configuration system with easy switching between different setups (simpler

than changing $PYTHONSTARTUP environment variables every time).

* Session logging and reloading.

* Extensible syntax processing for special purpose situations.

* Access to the system shell with user-extensible alias system.

* Easily embeddable in other Python programs.

* Integrated access to the pdb debugger and the Python profiler.
