Add missing "selectionHighlightBackground" key

[andreynering]

This is the key that highlights other identical words (those you can follow which command+D) when you select one.

The default was too close to white, almost invisible. Changing to a slightly darker grey.

@akamud Closed without a comment?

Sorry about that. I just released a new version today and the original issue seems fixed. Can you confirm if this is correct or if I misunderstood the issue please?

@akamud I just updated and the selection is still too light for me, too similar to white, hard to see.

And the selectionHighlightBackground key is still missing on the OneLight.json: https://raw.githubusercontent.com/akamud/vscode-theme-onelight/master/themes/OneLight.json

Can you please attach some screenshots? When I was testing the editor was using a dark color for me. Maybe I'm missing something.

As I said, I found it quite hard to see matched words. I'm using this on settings.json for now to override it:

{
  "workbench.colorCustomizations": {
    "[Atom One Light]": {
      "editor.selectionHighlightBackground": "#eaeaeb"
    }
  }
}
