Started undoing the assumption $ === jQuery which does not hold if jQuery.noConflict() was called.
Created new method in PanelManager so panels can constructed using JavaScript after loading the setup saved locally or on the server, checking if such a panel already exists. Changes to handle the initialization timing using callbacks. Actually started using Panel's Config attribute, added an img alt attribute for closing panels even if the image is missing. Some coding cleanup.
