Layout JS: changed initShareDialog() with initStatefulURLUpdate()    This replacews the Share dialog behavior, with simply updating the address bar in-place every 3 seconds
Admin: improved handling of error condition, when you try to request a submission that does not exist. now properly closes spinner and alerts
Admin: the tablerowCallback used for populating the table, now properly has the 'type' parameter added so it works for more than just notes (which had been hardcoded as a placeholder)
Admin: when bringing up info on a submission, the callback will 'check' the checkboxes to make map layers visible, corresponding to the selected submission. thus,one can no longer zoom to a Declined Polygon... and yet see nothing because they have Polygons/Declined not visible on the map
