use pyzmq tools where appropriate...
use pyzmq tools where appropriate ZMQStream is the right object to use for event-driven handling of messages, but instead we chose to rewrite half of it in KernelManager. This removes most of the duplicate code, in favor of using ZMQStream. also use the pyzmq install() function for using pyzmq with tornado, instead of manually pasting its contents in notebook app.

Add ipy_signals for better ctrl + C processing
r477 """ Advanced signal (e.g. ctrl+C) handling for IPython
So far, this only ignores ctrl + C in IPython file a subprocess
is executing, to get closer to how a "proper" shell behaves.
Other signal processing may be implemented later on.
If _ip.options.verbose is true, show exit status if nonzero
