- update to 0.9.10:
  * Fixed unit test that hangs on Windows
  * Fixed bug where the ``set`` command was not tab completing from the current ``settable`` dictionary.
  * Changed edit command to use do_shell() instead of calling os.system()
  * Fixed issue with echoing strings in StdSim. Because they were being sent to a binary buffer, line buffering
    was being ignored.
  * Made quit() and exit() functions available to scripts run with pyscript. This allows those scripts to exit
    back to the console's prompt instead of exiting the whole application.
  * Fixed bug when user chooses a zero or negative index when calling ``Cmd.select()``
  * Restored behavior where ``cmd_echo`` always starts as False in a py script. This was broken in 0.9.5.
  * **cmdloop** now only attempts to register a custom signal handler for SIGINT if running in the main thread
  * commands run as a result of ``default_to_shell`` being **True** now run via ``do_shell()`` and are saved
    to history.
  * Added more tab completion to pyscript command.
  * Deleted ``Cmd.colorize()`` and ``Cmd._colorcodes`` which were deprecated in 0.9.5
  * Replaced ``dir_exe_only`` and  ``dir_only`` flags in ``path_complete`` with optional ``path_filter`` function
    that is used to filter paths out of completion results.
  * ``perror()`` no longer prepends "ERROR: " to the error message being printed
  * Fixed bug introduced in 0.9.5 caused by backing up and restoring `self.prompt` in `pseudo_raw_input`.
    As part of this fix, continuation prompts will not be redrawn with `async_update_prompt` or `async_alert`.
  * All platforms now depend on [wcwidth](https://pypi.python.org/pypi/wcwidth) to assist with asynchronous alerts.
  * Macros now accept extra arguments when called. These will be tacked onto the resolved command.
  * All cmd2 commands run via `py` now go through `onecmd_plus_hooks`.
  * Fixed bug where ``get_all_commands`` could return non-callable attributes
  * Fixed bug where **alias** command was dropping quotes around arguments
  * Fixed bug where running help on argparse commands didn't work if they didn't support -h
  * Fixed transcript testing bug where last command in transcript has no expected output
  * Fixed bugs with how AutoCompleter and ArgparseFunctor handle argparse
    arguments with nargs=argparse.REMAINDER. Tab completion now correctly
    matches how argparse will parse the values. Command strings generated by
