Option to redirect ipython notebook log output to file

I have been combing over the documentation to see if this was already implemented, but I am not seeing it. Basically, it would be great if there was some flag passed to `ipython notebook` to dump logs to some standard place like `$HOME/.ipython/profile_*/notebook-NNNN.log` kind of like how engine and cluster logs are handled. This is really great when working remotely and I would like to grab the log as opposed to try some hacky redirection. This additionally could be combined with a fork so as to return the user to their prompt.
