Submitting a popup (such as a login popup) not directing the user to the parent page that initially spawned the popup

New logic that extends the js Drupal settings in Popups.addJS() uncovered the fact that the original Path was not getting set correctly in Popups.openPath(). Submitting a popup (such as a login popup) was not directing the user to the parent page that initially spawned the popup. I’ve created a patch to handle this correctly now.
