Add parseDocument, which builds a full HTML document by the HTML5 tree-construction insertion modes (initial, before html, before head, in head, after head, in body): - the result always has an html root containing a head and a body, whether or not the source spelled those elements out. - head-only elements (title, meta, link, base, style, script, and the rest) are routed into the head; flow content starts and fills the body. - explicit html, head, and body tags and their attributes are honored. The existing fragment parser (parse) is unchanged, so tag-soup fragments still round-trip without an implied wrapper. Closes #69
