[whatwg] HTML differences from HTML4 document updated

[Simon Pieters]

Hi

The past few days I've been working on updating the HTML differences from  
HTML4 document, which is a deliverable of the W3C HTML WG but is now also  
available as a version with the WHATWG style sheet:

Review welcome. Please file bugs.
