To implement form controls internally in LibWeb (necessary for multi process forms), we'll need the ability to handle events since we can't rely on LibGUI widgets anymore. A LayoutNode can now override wants_mouse_events() and if it returns true, it will now receive mousedown, mousemove and mouseup events. :^)
