added missing delegate implementation in ResponseWrapper

[Born2Go]

this missing delegate causes a null pointer exception when using "public void cookie(String path, String name, String value, int maxAge, boolean secured, boolean httpOnly) "

I just run into a similar issue: methods
public int status()
and
public String type()
are missing overrides in ResponseWrapper, too.

I tried accessing response.status() in my after-wrapper and ran into a NPE.

Maybe these should be overridden as well?
