[whatwg] Update to the Adoption Agency Algorithm

[Ian Hickson]

Just a note to those of you who reviewed the new parsing rules yesterday: 
I changed them today to take into account some feedback from Hyatt. 
Basically the old algorithm was creating too many nodes. This is now 
fixed, the algorithm only moves the nodes that are being closed, not the 
other inlines it happens to cross.
