Upgrade to release 3.0.19:
- Make the flush method of the vt100 output implementation
re-entrant (fixes an issue when using aiogevent).
- Fix off-by-one in `FormattedTextControl` mouse logic.
- Run `print_container` always in a thread (avoid interfering with
possible event loop).
- Make sphinx autodoc generation platform agnostic (don't import
Windows stuff when generating Sphinx docs).
