Replace solarized-dark-grey-nodes.css with a settings.js configuration

[ristomatti]

Node-RED supports setting node colors in settings.js. This removes the need for awkward CSS trickery to change the node colors in CSS. The CSS colors need to be moved to a JS/JSON file which can then be required directly from node_modules in settings.js.

Settings file syntax for reference:

{
  editorTheme: {
    palette: {
      theme: [
        // Override node colours - rules test against category/type by RegExp.
        { category: ".*", type: ".*", color: "#f0f" }
      ]
    }
  }
}
