Update ipython to 5.3.0

IPython 4.0
===========

Released August, 2015

IPython 4.0 is the first major release after the Big Split.
IPython no longer contains the notebook, qtconsole, etc. which have moved to
jupyter <https://jupyter.readthedocs.io>.
IPython subprojects, such as IPython.parallel and widgets have moved to their
own repos as well

IPython 5.0
===========

Released July 7, 2016

New terminal interface
----------------------

IPython 5 features a major upgrade to the terminal interface, bringing live
syntax highlighting as you type, proper multiline editing and multiline paste,
and tab completions that don't clutter up your history.

These features are provided by the Python library prompt_toolkit,
which replaces ``readline`` throughout our terminal interface.

Relying on this pure-Python, cross platform module also makes it simpler to
install IPython. We have removed dependencies on ``pyreadline`` for Windows and
``gnureadline`` for Mac.

Backwards incompatible changes
------------------------------

- The ``%install_ext`` magic function, deprecated since 4.0, has now been deleted.
  You can distribute and install extensions as packages on PyPI.
- Callbacks registered while an event is being handled will now only be called
  for subsequent events; previously they could be called for the current event.
  Similarly, callbacks removed while handling an event *will* always get that
  event.
- Integration with pydb has been removed since pydb development has been stopped
  since 2012, and pydb is not installable from PyPI.
- The ``autoedit_syntax`` option has apparently been broken for many years.
  It has been removed.
