* fix/refactor backlight stuff: - fix colors dont turn of when backlight 0 and black is set - add option to use not colored backlight - fix colored backlight not colored on very low color values - various code style tunings * apply needed change to wizard * backlight disabled on static color and efects * fix warnings * try fix udp compiler warnings
