Changes for 2.0.4

• Fixed the TypeScript declaration of GraphObject.make to allow an HTMLDivElement as an argument when building a Diagram. Also added some type overloads of that function to reduce apparent type errors with correct code.
• Fixed some apparent non-determinism in the results of LayeredDigraphLayout upon an initial layout.
• Animation upgrades, notably when you move a port during an animation, connected Links will properly re-route.
