devel/py-game: Update 1.9.1 -> 1.9.5; ndowens.fbsd@yandex.com takes maintainership

The PR also contained the rename py-game -> py-pygame. I didn't rename it, IMO it isn't
urgent, and can be done later if really needed. There are quite a few ports that have a
similar name mismatch (missing "py" in the name).
