This pull-request close #82, by changing our ReadLine implementation to return a magic error if the user presses Ctrl-C twice in a row. This then triggers a restart of the CCP. This only works in the CCP, and in programs it launched. If a user presses this combination otherwise it will terminate the emulation. In a real CP/M system Ctrl-C would reload, but it is too easy to accidentally press, so I ensure it is two consecuitive Ctrl-Cs that triggers this behaviour.
