Create from_borrowed and from_owned constructors for IceResult and BreadcrumbTreeElement.

Browse Source 
In an effort to keep track of how often memory is getting heap allocated, I am implementing constructors for IceResult and BreadcrumbTreeElement. This should limit the places that I call Rc::new and allow me to place tracing code into it later to ensure all code paths doing heap allocation make sense.
