Title: Use virtual property

Fixed:
1.Disable CACHE_TEXTTURE_DATA on blackberry playbook port
2.Make the property functions to virtual type. CCSprite has a virtual function setRotation, if CCNode's property of setRotation is not a virtual function, it will cause some bugs.
3.Add CC_SYNTHESIZE_RETAIN macro.
