eliminate Template echoing on each action

```echo Template::instance()->render("default.html");``` was unnecessary on each action. We can eliminate it by binding action's name on a view with the same name;

So getting ```/module/action``` will display ```action.html.```

Also, when our application starts to scale we would need some more controllers. So i would add a folder controllers to place each modules controller and also separate views with a folder for each controller.
