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

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.

Updates on the brightness plugin to act like a menu so it will close the popup when it doesn't have input focus
