Added licenseID to learning designs in the FolderContentDTO. This allows the Flash client to list the license type in the workspace window, rather than having to request the whole learning design just to get the license details.
LDEV-73: The creative commons license icons are made up four components. assets/license_images are the original files used to make up the icons - the gifs are the component images and the xcf files are the Gimp files (with layers) that are used for making up the combined images and saved as jpegs. The jpegs are in the images/license directory in lams-central.
LDEV-73: Updated license data to include references to the license images (stored in lams-central/web/images/licence) and updated urls and names for the 2.5 creative commons licenses.
