MapLoom: Login triggers return to homepage

[slibby]

If you are in the map viewer, and you want to login to start editing one of the layers, the login process takes you away from the map with no way to return to your prior layer list or extent.

If you are logged in and viewing someone else's map you can save a copy to keep your extent and layers. If you click the save button, it should prompt you. If you are not logged in, then there's nothing we can do without changes upstream. If you are viewing a new map, after you login it should return you to http://ebolageonode.org/maps/new. Is that the page you are referencing? In my testing it does not return you to http://ebolageonode.org.

Currently, MapLoom does not use the History API (https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Manipulating_the_browser_history) since it is embedded in an iframe. Dropping the iframe and adding directly to the page adds significant complexity since then the GeoNode and MapLoom javascript/css/resources can conflict.

One potential solution might be use of the Shadow DOM (http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom/). However, any solution will require significant work and will likely not be complete within the next few months.
