Issue #1655: Update MediaQueryList to the current draft spec.
This make MediaQueryList inherit from EventTarget and adds MediaQueryListEvent as an interface as well as the onchange() method. This should not affect compatibility with other code; the event object is a MediaQueryListEvent instance, which is recognized as a MediaListQuery instance.
