Add Julia to default script magics....

Add Julia to default script magics. I have been adding this line manually to my local copies of IPython/Jupyter and even suggest to do so in a Stack Overflow question, it would be nice if this worked by default. https://stackoverflow.com/questions/24091373/best-way-to-run-julia-code-in-an-ipython-notebook-or-python-code-in-an-ijulia-n/24106944#24106944 Should I also add R or any other language? Is this not the correct way to do it? Please let me know, cheers!
