Create an API for modules in Java side declared by dynamic Javascript files

[hdsdi3g]

With #281 and Nashorn API.

Usage in Java side:

MyDMAM.factory.getInterfaceDeclaredByJSModule(MyInterface.class, "module name", () -> {
 return (class manually crafted);
});

With MyInterface.class:

public interface MyInterface {
  public String helloWorld(String me);
  public String toto();
  public Collection<String> arr();
  public Map<String, String> amap();
}

And, in JS side:

module.register({
  name: "module name",
  vendor: "Meeee",
  version: "0.1",
  content: {
    helloWorld: function(e) {
      return "Hello world, " + e;
    },
    toto: "aa",
    arr: ["Merci", "Test"],
    amap: {
      aaa: "bbb",
      ccc: "ddd",
    },
  },
});
console.log("Done");

The JS file must be set in conf/app.d directory.
