1.4.0

• Rework keyboard backlight mechanism. Users need to repatch DSDT. More specific, the line ^^KBLV = Arg0 / 16 must be removed.
• Rework ambient light sensor mechanism (use WMI for toggling sensor; read value directly with method _ALI). DSDT patch is not needed anymore.
• Add experimental support for reading fan speed with WMI
• Support battery charge threshold found on new laptops (charging stops at 80%). Can be disabled by turning off Battery Health in Energy Saver.
