We now only preserve the whitespace inside a <t> element inside the parser. This removes the known n^2 from reattaching whitespace which should make parsing and appending nodes faster. I also removed the dead WhitespaceMode code from the parser, and made the dom-seralizer.sky auto indent the markup so the test output would be readable.
