GET Parameters on generated URL

[luiz]

Currently, when an URL to a method is generated and this method receives some arguments, only those that change the URL's base are inserted in the generated URL. For example, suppose you have the following controller method:

public class PostsController {
    @Path("/users/{user.id}/posts")
    @Get
    public void listPostsFrom(User user, String tag) {...}
}

And you want to generate the URL /users/1/posts?tag=testing. The current behavior is, when generating an URL using

url(); to(PostsController.class).listPostsFrom(userWithId1, "testing");

is to generate the URL /users/1/posts, without the parameter tag because it's not part of the base URL. But it should generate the desired URL, described above.
