This introduces 3 classes: NodeList, StaticNodeList and LiveNodeList. NodeList is the base of the static and live versions. Static is a snapshot whereas live acts on the underlying data and thus inhibits the same issues we have currently with HTMLCollection. They were split into separate classes to not have them weirdly mis-mashed together. The create functions for static and live both return a NNRP to the base class. This is to prevent having to do awkward casting at creation and/or return, as the bindings expect to see the base NodeList only.
