BUG: Switched to new way of registering ipython magics

[KristianHolsheimer]

Hi Robert,

Thanks for the awesome package, it's been a lifesaver on many occasions!

This is a minor change, implementing the new way of registering ipython magics. Namely, get_ipython().define_magic(...) was apparently deprecated. The new way uses get_ipython().register_magic_function(...) instead. I did leave the old one in for backward compatibility.

Cheers, -Kris

This doesn't work for me IPython 5.1, Python 3.5: %lprun -f ....

This is not sufficient, the signature to magic functions has changed, #65 is the correct fix.

Fixed by the 2.0 release.
