Deprecated function: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in _views_slideshow_preprocess_views_slideshow()

PHP 5.5 bawls about the /e modifier. Not safe, not cool etc.

Please change to preg_replace_callback, which works always, everywhere, all the time.

(It's not really a bug, since Drupal 7 supports PHP 5.2, so I guess it's a task...)
