Comment 15 for bug 207183

Fix committed in 0.57 moblin-applets. I changed the libbrightnesscontrol code to read the value of the laptop_panel.num_levels value in the HAL laptop_panel namespace. This value is the number of discrete brightness levels, and the new behavior seems to be that the actual levels are 0-num_levels-1. I updated the libbrightnessconrol library and the brightness applet and moblin-settings-daemon (which sets the brightness for shortcut keys). It appears to work well now.
