[Feature request] Automatically enable colorTheme: dark on prefers-color-scheme: dark

[KaKi87]

Hello,

prefers-color-scheme allows users not to have to manually change theme settings in every webapp they visit when they already set their browser and/or system theme as dark.

Therefore, it would be nice of StackEdit to automatically add colorTheme: dark to settings when prefers-color-scheme: dark is set.

As an alternative I tried to use localStorage.setItem from a userscript, but without success, because of the hash property I suppose.

Thanks
