 widgets.php calls sanitize_title() on widget IDs.  For the new API
 (functions starting with wp_), this isn't necessary.  sanitize_title() is
 a slow function that does lots of stuff we don't need to do when
 sanitizing an ID.  Let's just drop the sanitization and take the ID as is.
 For the old widgets API (functions without wp_), the sanitization can stay
 for maximum back-compat.
