Currently the slider represents a gamma adjustment to the brightness curve when auto brightness is enabled and the absolute screen brightness when it's not. This is a fairly confusing behavior to most people, so this consolidates them to a single behavior: the slider always represents the current brightness and auto-brightness will automatically adjust it. This also moves a bunch of the brightness methods from PowerManager over to DisplayManager, since it's really the DisplayPowerController that's responsible for determining and setting the display brightness.
