* Renamed treeView.js to folderTreeView.js (more changes on this file forthcoming) -- this will soon be specifically for folders.
* Added itemTreeView.js, with new Scholar.ItemTreeView class -- specifically for items.
* The items list now supports 3 additional columns: rights, date added, and date modified.
* For now, selecting an item loads the "I'm Feeling Lucky" result of a Google search on the item title.
