We modify the panorama XML in certain parts of the tour,
but problem is, openNext() loads the cached version of the xml..
we can use pano.readConfigUrl(..+randomnum) to refresh the current view,
but when we continue using minimap (openNext), it loads the cached xml again..
any ideas how to fix that,
as we still want to use cache,
but would need to refresh one xml that has been updated
so that it works with openNext()..
