Jelle Raaijmakers 4e51e585a2 LibWeb: Only show namespace if non-default in DOM tree dump
When dumping the DOM tree, only prefix the element's local name with its
short namespace identifier if it's not the document's default namespace.
This gets rid of the excessive "html:" and "svg:" prefixes in context of
an HTML or SVG document, respectively.
