* Added a new tool to create & run cocos2d-html5 and JSB project
* cc.Application -> cc.game
* `coco2d.js` is replaced by `project.json`
* Supported `Attributes` getter/setter for some classes,
* Added `node.attr` function to initialize properties
* Supported 3rd resource loader

I am not sure if i modified correctly or not.
Please take a look.
