Automate Dark Mode

With ios 13 a dark mode would be great, which would be influenced by the OS settings (have the automatic dark mode)

btw. im on mobile, ill fix typos tomorrow

@Anatoly Codea 3.0 has a setting for this — the editor theme can use dark or light mode depending on the system setting if you switch it to “Automatic” in the settings panel.

Oh. Right. I really need to update codea on my ipad.
