Observer free code path for state

[wied03]

For those of us that use the GrandCentral/Redux approach and keep most state outside the component, we don't want to hit any Observable code for any incidental state calls. I'm assuming that any Observable code remains light to keep file sizes down.

@wied03 I agree that observable state shouldn't be required. This could be addressed in the state definition by passing an option. Not sure if it should be opt in or opt out, but I like declaring it for the purpose of having self documenting components.
