Updated component to use CCUIBackground. Added ability for CCUIBackground to draw a solid color background. Changed NodeBox to allow for an extra child node (the background node). Added CCUIBackground.js to be loaded as part of Cocos.
Added support for padding to the background logic in Component.
Added support for image backgrounds
Merge branch 'background_dev' of https://github.com/myoung-zynga/cocos2d-html5 into background_dev
Finished merge of color and image backgrounds. For now it is using a sprite to do the backgrounds, but in the future it needs to use the context.drawImage method (see the TODO).
Added comments for new methods to finalize this feature implementation.
Merge pull request #4 from myoung-zynga/background_dev

Background Development, still a work in progress
