add escape_unfocuses field to PyCUI

[tadeaspaule]

More control over Escape / focus behavior. For use cases like single-widget applications and those that never want to go out of focus mode

• I have read the contribution guidelines
• CI Unit tests pass
• New functions/classes have consistent docstrings

What this pull request changes

• add escape_unfocuses field to PyCUI objects, default True. If set to False, user can provide widget-specific behavior for when Esc is pressed.

Issues fixed with this pull request

• Add callbacks for widgets gaining/losing focus #135 (with escape_unfocuses == False you can do widget.add_key_command(py_cui.keys.KEY_ESCAPE, foo))

I've thought about this, and would it perhaps be better to have the unfocus key be settable? With KEY_ESCAPE just the default? We could even add the option to set it to None so that there is no default unfocus key

Agreed
