* Bug Fixes
* Fixed extra space appended to each alias by "alias list" command
* Enhancements
* New function `set_default_ap_completer_type()` allows developer to extend and modify the
behavior of `ArgparseCompleter`.
* Added `ArgumentParser.get_ap_completer_type()` and `ArgumentParser.set_ap_completer_type()`. These
methods allow developers to enable custom tab completion behavior for a given parser by using a custom
`ArgparseCompleter`-based class.
* 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()` allows developers to specify custom
parameters to be passed to the argparse parser's `add_argument()` method. These parameters will
become accessible in the resulting argparse Action object when modifying `ArgparseCompleter` behavior.
* Using `SimpleTable` in the output for the following commands to improve appearance.
* help
* set (command and tab completion of Settables)
* alias tab completion
* macro tab completion
* Tab completion of `CompletionItems` now includes divider row comprised of `Cmd.ruler` character.
* 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.
* Deletions (potentially breaking changes)
* Deleted ``set_choices_provider()`` and ``set_completer()`` which were deprecated in 2.1.2
