Add more detailed scopes to C# language rules, to allow finer syntax coloring control

Feature Request Description

I'd like to be able to set different colors for different storage modifers like public and private, in C# code. For this I believe we'd need more detailed scopes.
Right now, both the public and private modifier has the textmate scope storage.modifier.cs, source.cs, which means it's impossible (?) to distinguish between them when coloring.

Suggestion

Add finer scopes, such as storage.modifier.public.cs for the public modifier, and so on.
So that settings like these would work in VS Code:

"editor.tokenColorCustomizations": {
  "textMateRules": [
    {
      "scope": "storage.modifier.public",
      "settings":{"foreground": "#F00"}
    }
  ]
}

Example of what does not work right now, as storage.modifier.public does not exist.
