Title: callbacks: this is optional

Instead of: ( [] means optional )

```js
item.setCallback( this, callback_fn );
cc.MenuItemFont.create("Hello", this, callback_fn);
cc.CallFunc.create( this, callback_fn, [data]);
```

The new API is: ( [] means optional )
```js
item.setCallback( callback_fn, [this] );
cc.MenuItemFont.create("Hello", callback_fn, [this] );
cc.CallFunc.create( callback_fn, [this], [data] );
```
