Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

LibHTML: Add support for <body bgcolor="#rrggbb" text="#rrggbb"> This patch implements basic support for presentational hints, which are old-school HTML attributes that affect style. You add support for a presentational hint attribute by overriding Element::apply_presentational_hints(StyleProperties&) and setting all of the corresponding CSS properties as appropriate. To make the background color fill the entire document, not just the bounds of the <body> element's LayoutNode, we special-case it in the HtmlView::paint_event() code for now. I'm not entirely sure what the nicest solution would be, but I'm sure we'll discover it eventually.

LibWeb: Move ARIA-related code into the Web::ARIA namespace ARIA has its own spec and is not part of the DOM spec, which is what the Web::DOM namespace is for (https://www.w3.org/TR/wai-aria-1.2/). This allows us to stay closer to the spec with function names and don't have to add the word "ARIA" to identifiers constantly - the namespace now provides that clarity.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.

LibWeb: Add a whole bunch of HTML DOM bindings Note that these aren't full implementations of the bindings. This mostly implements the low hanging fruit (namely, basic reflections) There are some attributes that should be USVString instead of DOMString. However, USVString is a slightly different definition of DOMString, so it should suffice for now.

LibJS+Everywhere: Allow Cell::initialize overrides to throw OOM errors Note that as of this commit, there aren't any such throwers, and the call site in Heap::allocate will drop exceptions on the floor. This commit only serves to change the declaration of the overrides, make sure they return an empty value, and to propagate OOM errors frm their base initialize invocations.

LibWeb: Basic implementation of global event handlers :^) Document and HTMLElement now inherit from HTML::GlobalEventHandlers which allows them to support "onfoo" event handler attributes. These are assignable both via IDL attributes and content attributes. Event listeners constructed this way get a special "attribute" flag on them so we know which one to replace if you reassign them. This also allows them to coexist with EventTarget.addEventListener(). This is all a bit sloppy, but it works decently for a first cut. The Window object should also inherit GlobalEventHandlers, but since we don't generate it from IDL, I haven't taken that step here. Also this would be a lot nicer if we supported IDL mixins.
