Add system theme switching support #959

Open thrust26 opened 1 year ago

Today's OS allow automatic switching themes depending e.g. on the daylight.

Future SDL Versions will support querying the API, using SDL_GetSystemTheme(). If this is supported, Stella should support switching themes automatically. The user should be allowed to select different themes for day (default light) and night (default dark) time.

A SDL_EVENT_SYSTEM_THEME_CHANGED is sent when the system theme changes
