Fixed Build Errors with Cocos2d 3.0

Docs aren’t clear, but I think this is the correct API transition.

Changed self.isRunning to the new method self.isRunningInActiveScene

CCArray has been replaced with just a NSArray. Using normal for() loop
to iterate children.
Updated .gitignore

Added *.xcuserdatad
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.
