Change color mode quick switch behavior

Right now, the color mode button in the quick switch panel simply switches on and off the color mode function, without altering the setting. This is fine in most cases, but if you have color mode set to "night mode" and "automatically change", this is not ideal. In fact, during the day it does nothing, since even if you enable it, the "auto" setting will prevent it to display night colors.

I would propose one of the two following options:

A) leave the behaviour like this, except that if you are in "auto night mode", the button will override the current setting (i.e. switch to night mode if the current automatic color mode is day, and to day mode if the current automatic color mode is night).

B) transform it in a circular switch that cycles through the following states every time it's pressed:

day->night->night auto->high contrast->low contrast
