Simplifying the namespace.
Creator generator to support only the default instantiable types.
Made the Http to work but it is not working the "right way"

https://github.com/kyoken74/gwt-angular/issues/3
Still clean up Deferred interface.
Added support for Http.onNotify(Request)

The Request object from RequestBuilder can be used to cancel pending
http requests, so, it is passed to the callback via onNotify. The 
caller must keep the state, however, if he wishes to retain the ability
to cancel the request.
Splitting HTTP out to its own GWT module because it relise on RequestBuilder.
Cleaning up the gwt.xml dependency.
JSFunction added. NOT YET TESTED
