Await helper: Make it possible to set a value to be returned before the given promise is settled

[Schnellesadlerauge]

Makes it possible to set a value to be returned until the given promise has settled

{{await model.title 'loading...'}}

I need it for a case where I want to set a property only to false when the promise resolves with false

readOnly={{await (get-something-with-a-api-call "foo" "bar") true}}
