Final cleanup work...

1) Eliminate need for a GUISkin for the controller UI.
2) Make modifier keys for UI customizable.
3) Add a toggle key combo so the UI isn't always in the way.
4) Improve demo UI scene to include more color conflicts and an example of UnityGUI being affected by this filter.
5) Ditch physics for demo.
Reorganize assets a bit.
