- update to 2.2.0:
* Fixed extra space appended to each alias by "alias list" command
* New function `set_default_ap_completer_type()`
* Added `ArgumentParser.get_ap_completer_type()` and
`ArgumentParser.set_ap_completer_type()`.
* Added `ap_completer_type` keyword arg to `Cmd2ArgumentParser.__init__()`
which saves a call to `set_ap_completer_type()`. This keyword will also
work with `add_parser()` when creating subcommands if the base
command's parser is a `Cmd2ArgumentParser`.
* New function `register_argparse_argument_parameter()`
* Using `SimpleTable` in the output for the following commands
* Tab completion of `CompletionItems` now includes divider row
* Removed `--verbose` flag from set command since descriptions always show now.
* All cmd2 built-in commands now populate `self.last_result`.
* Argparse tab completer will complete remaining flag names if there are no
more positionals to complete.
* Updated `async_alert()` to account for `self.prompt` not matching Readline's
current prompt.
* Deleted ``set_choices_provider()`` and ``set_completer()`` which were
deprecated in 2.1.2
