LibWeb: Implement the first half of the Adoption Agency Algorithm The AAA is a somewhat daunting algorithm you have to run for certain tag when inserted inside the <body> element. The purpose of it is to resolve issues with mismatched tags. This patch implements the first half of the AAA. We also move the "list of active formatting elements" to its own class, since it kept accumulating little behaviors. "Marker" entries are now signified by null Element pointers in the list.

LibWeb: Implement more table support in the new HTML parser This is enough to parse the Google front page! (Note: I did have to hack the tokenizer while parsing Google, in order to avoid named character references screwing everything up. We'll fix that too soon enough!)
