CCFollow.action cannot work

[ChenZhongPu]

In the test demo, the Follow Action should make the sprite be centered. However, it didn't work well as expected.

There is a bug in org.cocos2d.actions.base CCFollow.java .
Modify step routine as following code, then you will find the test demo works as expected.

public void step(float dt) {
...
target.setPosition(CGPoint.ccp(CLAMP(tempPos.x,rightBoundary,leftBoundary),
CLAMP(tempPos.y,topBoundary,bottomBoundary)));
...
}
