Scott Violet e98fd07ffb Fixes crash in HTMLIFrameElement and exposes HTMLIFrameElement::src
HTMLIFrameElement was adding the observer in navigateView. If the same
HTMLIFrameElement navigated multiple times HTMLIFrameElement would
attach itself as an observer more than once. ObserverList doesn't like
this.

Also adds src as an attribute of HTMLIFrameElement so that I can do:
iframe.src = xxx
in script
