Disable Google map recenter function in daily RDAHMM

In response to portal users' requests, we have disabled the "automatic recenter function" of Google map in the daily RDAHMM portlet. The trick turns out to be a "internally used" feature of the GMarker.openInfoWindowHtml() function, which is not included in the official online documents:

marker.openInfoWindowHtml(htmlStr, {suppressMapPan:true});
