* Bug Fixes
* Fixed issue where subcommand usage text could contain a subcommand alias instead of the actual name
* Fixed bug in `ArgparseCompleter` where `fill_width` could become negative if `token_width` was large
relative to the terminal width.
* Enhancements
* Made `ipy` consistent with `py` in the following ways
* `ipy` returns whether any of the commands run in it returned True to stop command loop
* `Cmd.in_pyscript()` returns True while in `ipy`.
* Starting `ipy` when `Cmd.in_pyscript()` is already True is not allowed.
* `with_argument_list`, `with_argparser`, and `with_argparser_and_unknown_args` wrappers now pass
`kwargs` through to their wrapped command function.
* Added `table_creator` module for creating richly formatted tables. This module is in beta and subject
to change.
* See [table_creation](https://cmd2.readthedocs.io/en/latest/features/table_creation.html)
documentation for an overview.
* See [table_creation.py](https://github.com/python-cmd2/cmd2/blob/master/examples/table_creation.py)
for an example.
* Added the following exceptions to the public API
* `SkipPostcommandHooks` - Custom exception class for when a command has a failure bad enough to skip
post command hooks, but not bad enough to print the exception to the user.
* `Cmd2ArgparseError` - A `SkipPostcommandHooks` exception for when a command fails to parse its arguments.
Normally argparse raises a `SystemExit` exception in these cases. To avoid stopping the command
loop, catch the `SystemExit` and raise this instead. If you still need to run post command hooks
after parsing fails, just return instead of raising an exception.
* Added explicit handling of `SystemExit`. If a command raises this exception, the command loop will be
gracefully stopped.
