The goal is to make implementing a renderer straight forward.
BREAKING_CHANGE:
- Renderer interface was redone / simplified.
- `DirectDomRenderer` was replaced by `DomRenderer`.
- `DirectDomRenderer.setImperativeComponentRootNodes` is replaced
by the following 2 steps:
1. `ViewManager.getComponentView(elementRef) -> ViewRef`
2. `DomRenderer.setComponentViewRootNodes(viewRef, rootNodes)`
- all `@View` annotations need to have a template, but the template
may be empty. Previously views that had a `renderer` property did
not have to have a `template`.
- `dynamicComponentLoader.loadIntoNewLocation` does no more allow
to pass an element, but requires a css selector.
Special syntax: `:document` can be used as prefix to search globally
on the document instead of in the provided parent view.
