Migration progression

TODO

Port SuperAnim to V3 or use Spine/CocoStudio/CocosBuilder
- probably a problem with new Renderer
- sent message to Raymond (SuperAnim maintainer) => no answer
- tried to modify draw() => doesn't work
- posted on cocos2d-x forum => no answer

CAN BE DONE LATER

use new Vector and Map structures
switch to std::function
use std::string everywhere possible, CCValue for the rest
use CCValue instead of CCFloat, CCBool and CCString
review all code to check that it follows new guidelines
refactor stats using DrawNode
re-add ExpansionSupport on Android as a module
re-add VideoPlayer and VideoRecorder on Android
