Title: replaced deprecated option /e with callable function

option /e was marked as deprecated since PHP 5.5.0

> ( ! ) Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in ~\libraries\joomla\filter\input.php on line 664

not sure if there's better way to make hex possible

regards,
Yurii
