Our decoration is deleted using deleteLater() and that might cause access
to the bridge. Given that we also need to deleteLater() the
PreviewBridge.
To do so the PreviewBridge is no longer directly exposed to QML, but
in a wrapper object which holds the bridge as only element.

- align with system palette
- base color for buttons and preview individually
to create a visual gap (make them more standalone)
- downsized button config buttons to match up w/ preview
appearance (and because it was simply to huge for a desktop thing)
- upsized preview to preferably show two elements at once
(current + 2*1/2context)
- made the titlebar a visible visual element
- label the titlebar "Titlebar"
- move the (altered) hint to the drag-from area
- hint draggability with a pointing hand cursor
- less hardcoded values
- brief animations on button adding/removing

The decoration button configuration interface is merged into the QML
part using two list views (left buttons, right buttons) and a grid
view for all the available buttons.
