[CCFileUtils] How about a set method for default root path of resources

Hi all!

In CCFileUtils the default resource path is set within the init() method to

m_strDefaultResRootPath =  + "/../../../Resources/"

In the comment of m_strDefaultResRootPath there is mentioned the following:

If the default root path of resources needs to be changed, do it in the `init` method of CCFileUtils’s subclass.

How about introducing an additional set method for changing easily from application level the default resource path?
An application writer is then not forced to make any changes on the framework.

I’m asking because I noticed that some people had already problems, like me, with the default resource path and were asking for help here.
