cmd2.Cmd.__init__ now initializes colorama and tells it to never strip ANSI codes since cmd2 deals with that

Also:
- Finished editing poutput(), ppaged(), and pfeedback() methods to strip ANSI color when appropriate
- Changed attr.ib() factory usage so cmd2 is compatible with older versions of attrs
