Please include colors for diffs

[ThiefMaster]

When viewing a .diff/.patch file there is currently no syntax highlighting - and since vscode doesn't have an option to use a different theme for certain file types I currently need to change the global theme away from this one temporarily if I want to view a diff file properly...

I was able to fix this by just copying in patch colors from a different theme. You can just add this in your user settings.json.

"editor.tokenColorCustomizations": {
  "[Darcula]": {
    "textMateRules": [
      {
        "name": "markup diff",
        "scope": "markup.changed.diff",
        "settings": {
          "foreground": "#e5c07b"
        }
      },
      {
        "name": "diff",
        "scope": "meta.diff.header.from-file,meta.diff.header.to-file,punctuation.definition.from-file.diff,punctuation.definition.to-file.diff",
        "settings": {
          "foreground": "#61afef"
        }
      },
      {
        "name": "inserted.diff",
        "scope": "markup.inserted.diff",
        "settings": {

  }
