GNOME Power Manager 2.21.1

[Richard Hughes <hughsient gmail com>]

GNOME Power Manager is a session daemon that makes it easy to manage the
power on your laptop or desktop system.

This _unstable_ release contains lots of crazy new code since 2.20.1 was
released. WARNING, this code may impregnate your cat called Dave and
steal all of the magazines from the bathroom.
