Implement Dark Mode support for Windows 10

[ZPNRG]

This isn't a huge priority to me personally, but it makes sense to add/support in time and the app probably would use less power as (I think) Dark Mode usually does on back-lit screens.

Any ETA on this ? Perhaps relying on other front-end libraries that allow for third party modifications could solve this issue, such as those which AcrylicMenus or TranslucentFlyouts are able to modify.
