Fixing up some Folder bugs

-> Rendering properly while in spring-loaded mode
-> Fixed bug where sometimes the folder's background would vanish
-> Fixed bug where the folder background was "stuck" in a fixed
   location, not following the folder
-> Can now add to folders and create folders from spring-loaded mode
