Title: Added script for load and install the extension.

OK, @bryevdv... I think this would fit better your original idea.
The script is called when you do:

`import bokeh.bokeh_magic`

And if it is not installed in the canonical way (IPython way), it will install and load the extension ;-)
So, the users do not have to be aware of the installation...
