UserInterface<T> class

A simple modal user interface layer.

It maintains a stack of screens. All screens in the stack update. Screens may indicate if they are opaque or transparent. Transparent screens allow the screen under them to render.

In addition, the interface can define a number of global KeyBindings which screens can use to map raw keypresses to something higher-level.
