Add init_environment(), %less, %more, %man and %clear/%cls, in zmq shell. These are all things that normally need direct terminal control and users are likely to call them via !, blocking their session because the pager will be invoked and we can't pass keystrokes to it. So for the zmq shell, we implement a few very common things as magics.
