Refactored sorting JS files to be includes so that server-side variables may be passed to them.

Added 'after_sorting_js_callback_name' attribute to SortableAdminBase.
Added callback to be executed after sorting for each of the possible sorting scenarios.
Added custom template examples to add a callback to be executed when sorting is finished.
