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.

4dde36844b LibWeb: Add a DOM Event class (instead of events being simple strings)
This patch adds the Event base class, along with a MouseEvent subclass.
We now dispatch MouseEvent objects for mousedown, mouseup and mousemove
and these objects have the .offsetX and .offsetY properties.

Both of those properties are hard-coded at the moment. This will be
fixed in the next patch. :^)

f39e5352f0 LibWeb: Start working on DOM event support
This patch adds the EventTarget class and makes Node inherit from it.

You can register event listeners on an EventTarget, and when you call
dispatch_event() on it, the event listeners will get invoked.

An event listener is basically a wrapper around a JS::Function*.

This is pretty far from how DOM events should eventually work, but it's
a place to start and we'll build more on top of this. :^)

b5a22fc408 LibWeb: Implement Document.getElementById()
This was pleasantly simple! We don't have an ElementWrapper yet, so it
just returns a NodeWrapper, but it still basically works. :^)

1c406294fc LibWeb: Start implementing basic JavaScript DOM bindings
This patch introduces the Wrapper and Wrappable classes.

Node now inherits from Wrappable, and can be wrapped in a GC-allocated
Bindings::NodeWrapper object. The only property we expose right now is
the very simple nodeName property.

When a Document's JS::Interpreter is first instantiated, we add a
"document" property with a DocumentWrapper object to the global object.

This is pretty cool! :^)

830a57c6b2 LibWeb: Rename directory LibHTML => LibWeb
Let's rename this to LibWeb since it aims to provide more parts of the
web platform than just HTML. :^)
