/**
 * API for deleting a bookmark.
 * The delicious API is implemented here.
 *
 * The delicious API behaves like that:
 * - returns "done" even if the bookmark doesn't exist
 *   - we do it correctly
 * - does NOT allow the hash for the url parameter
 * - doesn't set the Content-Type to text/xml
 *   - we do it correctly, too
 *
 * SemanticScuttle - your social bookmark manager.
 *
 * PHP version 5.
