fix/refactor backlight stuff (#394)

* 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
