update default behaviour of popups. now you can click and drag inside a popup without the events dropping through to the map, yet if you are dragging a zoombox over a popup, it still responds. this is all thanks to a new function i am adding to Util.js which is called OpenLayers.Util.safeStopPropagaition(). Turns out the default Event.stop() from prototype.js is also calling a function called preventDefault() which disallows things like selecting text or clicking a hyperlink. all tests pass.
