Upower 0.99 supports a composite display device that represents
the state of the computer. When that device type is around we will
use it to determine the panel icon, update the tooltip, and replace
the UP_DEVICE_KIND_LINE_POWER in the menu since it would be redundant.

The left click menu now displays the devices and their status at
the time of the menu's creation.

Rather than using a custom window migrate to custom items in a
GtkMenu. To that end, change from a GtkTreeView to GList internally.

Also put more trace/dbg messages in place so it's easy to track
these issues when upower breaks itself again in the future.

Dynamically changing the icon in the panel itself looks horrible.
Revert and improve it later.

This patch moves some code around, mostly putting shared stuff into
power-common inside common/. It also creates a new plugin to monitor
all the batteries in one icon on the panel rather than multiple icons
inside the system tray. It also removes the power-info application
as that will be moved inside the newly reworked settings dialog.

Hide settings menu only on desktop environment which have another
power manager, to make it appear on LXDE menu.

UPower dropped support for managing power. To continue to support
suspend and hibernate we'll add those functions into xfpm while
borrowing the helper code from xfce4-session.
