56ca91b9f8 LibWeb: Implement <script src> support for synchronous scripts
Scripts loaded in this way will block the parser until they finish
executing. This means that they see the DOM before the whole document
has been fully parsed. This is all normal, of course.

To make this work, I changed the way we notify DOM nodes about tree
insertion. The inserted_into() callbacks are now incrementally invoked
during parse, as each node is appended to its parent.

To accomodate inline scripts and inline style sheets, we now also have
a children_changed() callback which is invoked on any parent when it
has children added/removed.

7309642ca8 LibWeb: Use FlyString for Element tag names
This makes selector matching a lot more efficient, and also reduces the
number of strings on the heap.

9c9d3f0904 LibWeb: Parse <script> elements and run any JavaScript found inside
This patch begins integrating LibJS into LibWeb. Document holds the
JS::Interpreter for now, and it is created on demand when you first
call Document::interpreter().

We also add a simple "alert()" function to the global object.
