Auto dark theme on Android

[jjrpayne]

An option to auto-select the dark theme based on the user's system settings would be a nice feature.

Hi. I'm not sure if libgdx has an api for querying system theme, but I can add this to my to-do list for my rewrite, that is unfortunately long interrupted due to multiple consecutive health issues. I'll need to redesign the options dialog anyway.

I'd be interested in implementing this if I may contribute. I imagine it should be possible to pass the system theme through the Android launcher if an API query doesn't exist.

A draft implementation on the system_theme branch.

An improvement would be to select the black theme as dark theme, not as an extra option, so the theme would still be dynamic (light/black).

I don’t know. I don’t want to remove the ‘regular’ dark theme or overcrowd the options dialog. I’ve actually considered adding a fifth option, like 'system with black' or something, but four options already fill the entire height of the dialog 🙂.
