This patch series adds a ruby kernel for Jupyter/IPython.

At the moment, it's dependant on supporting wrapping as part of the
Ruby build system.

When run in a shell, iruby seems to crash, something which looks to be
fixed upstream, but not yet released (with [1]), however it does still
work when used from the Jupyter notebook.
