Add globals as a static of application

[bemky]

Support applications having static global to define properties passed to each view on display.

class App extends Application {
    static globals = app => {
        return { app }
    }
}

Should we call these helpers instead of globals ala Rails?

And should / how would application be set on globals ...

I'm going to remove this in favor of PR for layouts. Decided to suggest we move away from initializing view in display.
