[IPython-dev] make ctrl-c stop causing a crash exit with %gui and PyQt5

[Erik Hvatum]

Patch attached.  I think I'm fixing a straightforward oversight;
create_inputhook_qt4 wants a an InputHookManager object as its first
argument, not an InputHookBase.  However, we get away with supplying the
wrong object until someone hits ctrl-c.  Passing the right object makes
graceful ctrl-c event loop integration work properly, rather than causing
IPython to exit.

This seems familiar, but I'm not finding anything when I search.  Apologies
if this issue is old news :)

Cheers,
Erik
