1. change map on unordered_map for speeding json parse.
2. fixes crash when reload texture with alpha.
3. change reloadTexture(const char* fileName) to reload Texture(const char* fileName, unsigned int &imageWidth, unsigned int &imageHeight) for getting texture width and height.
4. add set CCDirector winsize just for cocostudio.
