Extend core classes

As with most projects I don't like modifying core files (although this project does present a unique case to do it). My proposal is as follows.

Split core directory into two structures

core/_boiler_.js
core/helpers/_helpers_.js

extend/_boiler_.js
extend/helpers/_helpers_.js

The Helpers extended module would look like this :

define(function(require) {

    var Helpers = require('core/helpers/_helpers_');

    return _.extend(Helpers, {

    });
});

The same would go for _boiler_. I would have these two modules configured in main.js in the require config to always load from extend\*. All new modules can now be created in extend allowing overrides of core files, helper files and new core extensions to be added without touching core itself.

Implement a Backbone style 'extend' static on core classes

So I stole the Backbone extend function and placed it into boilerplate. I have then modified all core classes to use the extend method as a static extend.

This allows

define(function(require) {

    var Boiler = require('boiler');

    return Boiler.ViewTemplate.extend({

        someMethod : function() {}

    });
});

I 'd like to know your thoughts, this structure works very well for me and I'm sure it'd work well for most that have used Boilerplate.js to bootstrap their projects.
