 *
 * A #PurpleSmiley is a base class for associating emoticon images and their
 * textual representation. It's intended for various smiley-related tasks:
 * parsing the text against them, displaying in the smiley selector, or handling
 * remote data (using #PurpleRemoteSmiley).
 *
 * The #PurpleSmiley:shortcut is always unescaped, but <link linkend="libpurple-smiley-parser">smiley parser</link>
 * may deal with special characters.
