ipython: modularize and enable more features

Add these new attributes (all default to true):

  notebookSupport
  qtconsoleSupport
  pylabSupport
  pylabQtSupport

This adds jinja2, matplotlib, pyqt4 and sip as new dependencies of
ipython.

This commit fixes "ipython --pylab" so that it no more errors out with
"ImportError: No module named matplotlib" (which was my initial goal).
Merge pull request #415 from bjornfor/ipython-pylab

Blender 2.66 WIP
systemd: Update to 199

This incorporates some changes from
https://github.com/vcunat/nixpkgs/commit/eb64a2f5620a9ba6ac7f598694d82db0cf83e669.
Delete all kernels older than 2.6.39

Systemd doesn't support those kernels, so there is no point in keeping
them around.
Linux kernel: Enable CONFIG_FHANDLE

This enables the open_by_handle_at(2) and name_to_handle_at(2)
syscalls.  Systemd kind of requires this.
man-pages: Update to 3.50
systemd: Enable the firmware loader in udev

It's needed in kernels < 3.8.
OpenImageIO Tidy Up: moved to applications/graphics

oiio includes CLI tools for manipulating graphics
Add OpenColorIO, a color management framework. Used by Blender
Add OpenColorIO support to OpenImageIO and tidy up
Rename oiio to openimageio (more explicit) and add opencolorio
Blender: enable extra features in the Video Sequence Editor

FFMPEG support allows a greater variety of export and import options.
SNDFILE support allows WAV and other sound file formats to be used.
JACK support allows blender to be used with XJadeo, Ardour or any other JACK away audio editor.
Blender: Tidy up, sort inputs, remove unused OPENJPEG option
Python 3.3 add setup-hook
Python 3.3 upgrade to 3.3.1rc1 to fix an important bug for Nix

http://bugs.python.org/issue15833

When Python 3.3.0 attempts to compile python bytecode in the system
directories it raises and exception and stops. Since Python 3.3 is
only required by the latest Blender, I hope it's OK to use the RC
until the final release.
Merge: use Python 3.3 as the default version of Python3
