pw_console: Style and help text cleanup
- Add high and low contrast dark UI styles.
- Add a toggle_light_theme option that uses ptpython's style
transformation which can change any theme into a light variant.
- Add Theme menu to toggle the above options.
- Add pygments-style-dracula and pygments-style-tomorrow.
- Set default pygments-style for python code to tomorrow-night-bright.
- Cleanup existing style classes.
- Highlight toolbars of the pane currently in focus.
- Add scrolling to help window content.
- Populate some Repl pane specific key binds in the help window.
- Allow for preable text in the help window content
- Allow F2 to trigger the ptpython repl settings. This allows users to
change python code themes among other things.
- Discovered F3 opens ptpython history window and it works.
- Add repl startup message option to embed()
- Add additional help text option to embed()
- TODO cleanup.
- Fix mouse_handler bug in get_pane_indicator
- Parse metadata from log lines.
No-Docs-Update-Reason: Cleanup change.
