Title: Change `SortableTreeView` to `sortable` option on `TreeView`

* Currently, `updateCount` propagation suppression works by checking for
the controller class name on the element, which breaks if the subtree
has a different class name.
* `SortableTreeView` was a simple enough change to move to be just an
option on `TreeView`.
