Also: - Added paged_output.py example - Modified cmd2 so it keeps track of when output is being redirected so it doesn't attempt to usage a pager in this case
It defaults to an empty string. But if a user would like a warning to be printed on a broken pipe error when using poutput() or ppaged(), then they simply set this to the warning they would like printed to sys.stderr.
Aslo: - Added some documentation for ppaged() - Updated CHANGELOG - Added line about ppaged() in README
