Macro for static resources

[sake92]

A very cool feature would be to have a macro that reads from src/main/public path and builds a tree of Resources. E.g. if you have this tree:

site
    ├───images
    │       favicon.ico
    ├───scripts
    │       main.js
    └───styles
            main.css

it would generate this:

object resources {
  object site {
    object images {
      val favicon_ico = resource("favicon.ico")
    }
// ... etc
  }
}

---

Then you could say just resources.site.image.favicon_ico.ref to get the path to favicon.ico. 😃
Since .ref returns a relative path, this would be very helpful.

Doesnt have to be a macro.. just a simple plugin/task
