Replace the remaining Node.removeChild() instances with Element.remove()

Browse source 
Using `Element.remove()` is a slightly more compact way of removing an element, since you no longer need to explicitly find/use its parent element.
Furthermore, the patch also replaces a couple of loops that're used to delete all elements under a node with simply overwriting the contents directly (a pattern already used throughout the viewer).
