Added support for Cocos2d 1.x and 2.x

Added method calls depending on what version of Cocos2d is being used.
Checks to see if the CCNode instance respondsToSelector.

1. isRunning on Cocos2d 1.x and 2.x
2. isRunningInActiveScene and userInteractionEnabled on Cocos2d 3.x

Removed my comments from the CCArray to NSArray loop changes.
Removed my comments from sf_isPointInArea and isPointTouchableInArea.
