Essentially, if an enclosure tag exists in the item, then the item menu will contain a link 'multimedia [speaker symbol]' to the media url. Otherwise, if there is no enclosure tag, there is no menu item shown. This feature required adding an enclosure column to the items table (models/schema.php) and bumping the DB version to 21 (models/config.php). I also added enclosure tag logic to the Rss20 parser, the model/item.php and template/item.php files.
