1) Rename com.google.gwt.requestfactory.shared.RequestObject<T> to Request<T>
2) Pull up com.google.gwt.requestfactory.shared.ProxyRequest.with(String...) into it
The goal is to some day be able to deprecate ProxyRequest and ProxyListRequest. Ideally we would be deleting them right now, but there is too much code in RequestFactoryGenerator, addon-gwt, and various tests that rely upon them. Again, do not deprecate them yet.
