options(feat[show_options]): Add public show_options() method

why: CHANGES documented Window.show_options() as replacement for
show_window_options(), but only private _show_options() existed.
what:
- Add show_options() public method to OptionsMixin as thin wrapper
- Add doctest examples for show_options()
