Update cocos2d_specifics.cpp

fix bug about scheduler, if this value is -1, it will work all right in Emulator, but run error in real device, just call one time.
Fix a memory leak in Set::removeAllObjects.
The set maintains a strong reference to all objects so release() should be called whenever something is removed from the set.
