The CmdResult helper class was deprecated in the previous release. This commit deletes it.
- The new CommandResult class is an improved replacement
Also:
- Deleted the namedtuple_with_two_defaults helper function which is now no longer used

If the `terminators` is the default, `None`, the function fails because the local variable was not updated.

These classes are subtly different, particularly in terms of their truthiness.
CmdResult
- attributes: out, err, war
- truthy: if err is falsy
CommandResult
- attributes: stdout, stderr, data
- truthy: if err is falsy AND data is not None
So CmdResult was oriented to provide essentially info, error, and warning messages to the user (typically as stirngs), whereas CommandResult is geared towards providing info and error messages to the user as strings in addition to data to the user in a command-specific format which is arbitrary other than it should never be None if the command succeeds.

Added a couple lines to the ppaged() docstring to help explain the advantages and disadvantages of chopping vs wrapping and when it would be best to do one as opposed to the other.
This should help developers understand the full potential of the ppaged() method.

over the end user
Specifically:
- PAGER environment variable is not used by default to set cmd2.Cmd.pager
- This is done to ensure a consistent behavior of cmd2 applications across users by default
Developers are free to set pager and pager_chop in the __init__() for their class derived from cmd2.Cmd differently to ensure whatever behavior they desire.
Also:
- Updated the paged_output.py example to demonstrate using ppaged() with both wrapped and chopped/truncated text

Changes include:
- pager is no longer a settable parameter which can be changed by the end user at runtime
- The cmd2.Cmd class now has two different attributes:
- pager
- contains command-line command to use to display wrapped text using a pager
- By default set to PAGER environment variable if it exists
- 'more' on Windows or 'less -RXF' on POSIX
- pager_chop
- contains command-line command to use to display chopped (truncated) text using a pager
- Set to same thing as pager unless pager starts with 'less', in which case a ' -S' gets appended
- The cmd2.Cmd.ppaged() method now has an additional optional argument "chop" which defaults to False
- If chop is True, then self.pager_chop gets used as the pager
- If chop is False, then slef.pager gets used as the pager
I couldn't think of any single solution which would somehow magically make all stakeholders perfectly happy. Hopefully this is a reasonable enough compromise that everyone feels that they can get what they need without too much pain ;-)
