UI Patterns Library: add some interactions

Postponed because we may target 2.1.0 instead of 2.0.0

Maybe we can simple place a block with the ui patterns form and render the preview with the configuration result?

Good idea. Is it possible to use such a form element without any storage? Can we limit the source at one max by prop, only widgets (textfield for strings, checkbox for boolean...) ?

I would store this in drupal state. Maybe the preview is part of the form. So we use drupal ajax to rerender. The form is without context so all sources with entity source are removed.
