PCHW course uses DNDs in which draggables ('initiators') are images, not text, and also includes images in some layout tables ('targetArea's). Digest tool was not processing image references in these locations, so these images were not getting included in the media library and relative references to webcontent were not rewritten in these sections. This change adds this processing for image references in the initiator or targetArea section of a custom drag and drop parallel to the handling already done for image refs in the DND style sheet.
