Corona LightMix - Reset

Right now it works as follows

Corona LightMix Reset setings to 1 - Restarts all the values to 1 and colors to 255,255,255
Corona LightMix Reset setings to 0 - Restarts all the values to 0 and colors stay the same

I would like to propose a #3 button “Reset colors” so that working with 1 and 0 is easier
