Support for configuring screen backlight

Accelerant interface:
Introduce new hooks B_SET_BRIGHTNESS and B_GET_BRIGHTNESS. Brightness is
a float in the 0..1 range.

App_server:
Forward brightness things between BScreen and the accelerant.

intel_extreme:
Implement the hooks. Note that this only works for laptop panels, but
the driver will pretend to support it in other cases as well.

Screen preferences:
If the accelerant supports the B_GET_BRIGHTNESS hook, allow to set
brightness with a slider. Otherwise, the slidere is hidden and these
changes aren't visible.

Fix glitch in Screen prefs when changing background color.

When both Backgrounds and Screen are open, if the workspace color is changed
in Backgrounds the monitor preview in Screen will now refresh to the new color.

Also added a BAlert in BackgroundsView.cpp when failing to change the
background image.
