restart channels on kernel restart...

restart channels on kernel restart generally not necessary, but sometimes the kernel connection can be dirty. We have only seen this by starting a qtconsole via %qtconsole, then killing the kernel, at which point the original notebook's connection (at the zmq level) is never restored to the new kernel at the same endpoint. It's weird, and probably a zmq bug, but a simple reconnect seems to solve it.
