allow keyboard interrupt to break out of ipdb
@takluyver @minrk and I discussed this issue in person.
It's currently problematic that there is no way, short of restarting a
kernel, to get out of an ipdb session if you've deleted the output of
the cell in the notebook which started it (by e.g. re-executing that cell).
This patch makes Ctrl-C behave the same as Ctrl-D inside of ipdb - it
exits the ipdb session. This also makes it possible to stop ipdb
sessions from another client.
I polled @katyhuff, @scopatz, and some other pyne/pyne hackers and they
were surprised to hear that this was not the behavior already.
