[gpm] The suspend and hibernate menu items

[Richard Hughes <hughsient gmail com>]

I'm thinking the suspend and hibernate menu items (when you left click
the battery icon) don't really work. The icon isn't shown if there are
no battery devices, and in some cases it's only shown when the
batteries are discharging or critical, so it's not always there. I'm
thinking of setting the GConf keys to default false for 2.27.x and
removing the functionality completely for 2.29. The user can still
click system -> shutdown -> suspend, or setup a icon on the panel to
do this, or if a laptop just shut the lid. What do you think?

Thanks.

Richard.
