LibWeb: Implement a slow but functional HTMLCollection :^)
HTMLCollection is an awkward legacy interface from the DOM spec. It provides a live view of a DOM subtree, with some kind of filtering that determines which elements are part of the collection. We now return HTMLCollection objects from these APIs: - getElementsByClassName() - getElementsByName() - getElementsByTagName() This initial implementation does not do any kind of caching, since that is quite a tricky problem, and there will be plenty of time for tricky problems later on when the engine is more mature.
