This patch adds a new HTMLDocumentParser class. It keeps a tokenizer object internally and feeds itself with one token at a time from it. The names and idioms in this class are expressed as closely to the actual HTML parsing spec as possible, to make development as easy and bug free as possible. :^) This is going to become pretty large, but it's pretty cool!
