[Enhancement] Adopt my dark theme for ZeroMe

I think people prefer this look over official ZeroMe's current dark style.

The current dark style you have is hardly dark and more so colorful. Mine strikes a balance: Dark, but not too dark.

I think it's a nice counterpart to the white theme.

Let's vote with the comments.
