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.

LibWeb: Create list-item markers during layout tree construction Previously, these were added during layout. This didn't fit into the new world where layout doesn't mutate the tree incrementally, so this patch adds logic to Layout::TreeBuilder for adding a marker to each list-item box after its children have been constructed.

LibWeb: Rename LayoutNode classes and move them into Layout namespace Bring the names of various boxes closer to spec language. This should hopefully make things easier to understand and hack on. :^) Some notable changes: - LayoutNode -> Layout::Node - LayoutBox -> Layout::Box - LayoutBlock -> Layout::BlockBox - LayoutReplaced -> Layout::ReplacedBox - LayoutDocument -> Layout::InitialContainingBlockBox - LayoutText -> Layout::TextNode - LayoutInline -> Layout::InlineNode Note that this is not strictly a "box tree" as we also hang inline/text nodes in the same tree, and they don't generate boxes. (Instead, they contribute line box fragments to their containing block!)

LibWeb: Let Paintable perform the painting This patch adds a bunch of Paintable subclasses, each corresponding to the Layout::Node subclasses that had a paint() override. All painting logic is moved from layout nodes into their corresponding paintables. Paintables are now created by asking a Layout::Box to produce one: static NonnullOwnPtr<Paintable> Layout::Box::create_paintable() Note that inline nodes still have their painting logic. Since they are not boxes, and all paintables have a corresponding box, we'll need to come up with some other solution for them.

LibWeb: Position the ListItemMarkers according to their width Previously they were positioned with a fixed offset. However this lead to wider markers with more than one character to collide with the element itself. Now the ListItemMarkerBox generates and stores the appropriate String in its constructor and sets its own width according to that. The ListItemBox then lays out the Marker taking this width into account. This also made the painting a lot easier since we don't generate the needed Strings every time we repaint, just once.
