Hal sends dbus signals when devices are added/removed and when properties are
changed. So if the battery level property is changed, you'll get an event. When
the power is connected (battery start charging), you'll get an event etc.. 

So the battery applet can be lazy and just do some fancy graphical stuff when
hal tells it something changed :)
