Only execute motion detection functions if features is enabled: Added compile switch around function and, in case the switch is on, an additional check if the features is activated by the settings. Added function to add an additional level of brightness to the backlight: The new interface allows to increase the brightness of the display on top of the normal setting. This may be used to indicate focus state to the user if motion detection is enabled
