Render correct HTML5 (#44)

Previously, elements of kind void and empty elements generally would be rendered auto-closing (with a final `/` character in the start tag), which is allowed sometimes but arguably wrong. See https://dev.w3.org/html5/spec-LC/syntax.html#end-tags

This created problems with for example `textarea` and `script`, which cannot be auto-closing, or the browser renders it wrong.

Also clarified in the docs that this library outputs HTML5.

Fixes #42.
