Add option to deactivate "system" dark mode for OnlineGo

[MisterFruits]

I love dark mode you've implemented for OnlineGo, that's a very useful option.

But, there is some trouble when dark mode is also activated at the system level, lot of white colors are converted into black: square for counting points, white stones in the main view (see images in comments).

Anyone with the same problem here ? How did you solve it ?

In the system dark mode preferences, lots of apps are available to deactivate dark mode specificaly but OnlineGo is not available in this list. I guess it would solve my problem. Maybe something should be activated in the code so that this option is available ? I found this, not sure whether it's relevant :
