wrapWith method in Model

[retro]

I've added wrapWith method to model that enables simpler inheritance for subclasses. I believe that wrap method shouldn't be overridden as it holds important functionality. This way user only has to overwrite wrapWith method that should return existing class.

It would be used like this:

$.Model.extend("Animal",{
  wrapWith: function( attrs ) {
        if(attrs.animal_type == 'dog') return Dog;
    if(attrs.animal_type == 'cat') return Cat;
    return this;
  } 
  },{}
});

I like this patch a lot!

I'm going to check with the guys, since I'm still nervous about committing directly to the main repo myself.

Yeah, I have pull privileges too, but would like if someone else would pull these changes.

meaning me it seems. I think either one of you can pull this if it's tested.
