Title: Check for isPrincipiaFolderish and image types in getFoldersAndImages

With these changes, any folderish content type could be used to check for any image_type instead of the hardcoded Folder and Image.
This should be a natural choice since there was a changeset that added Image and News Items to the images since there was an error when trying to display News Items
