if the browser doesn't support canvas,I think what i modify is better

```
p.insertBefore(s);
```

the above code  is similar to

```
p.appendChild(s);
``` 

but the canvas is also full screen, when the browser doesn't support canvas, we can't see the message, because the `Cocos2dGameContainer` div has the style `overflow: hidden`.

so, we should modify the code: 

```
p.insertBefore(s,d.getElementById(c.tag));
```

I think it's better!
