Update to html5-diff (ISSUE-65)

To facilitate with ISSUE-65 I updated html5-diff this afternoon:

   http://dev.w3.org/html5/html4-differences/

The main changes are done in the section named "HTML 5 Changelogs" which  
now summarizes the changes since the June 10 draft as well. I opted to  
keep the changes since January 22 in the document as well so people who  
check back once a year can use the document. Apart from that I made  
various editorial changes and updated the main document to reflect the  
current HTML5 draft.
