Re-implement my/page block drag and drop in dragula and jQuery We part ways with Protoype's Sortable module, link_to_remote, and some javascript in favor of a tigher implementation using dragula, jQuery, and some js.erb responses. Sorting logic was also simplified; we now merely send the state of the source and the target of the drag&drop to the server where it persists. We no longer make a special case for each of the containers. 9 years ago			`// Add partial to the top container.`
