Change to spl_autoload_register for autoload functions.  Auto load hook pages in construct as  shouldn't be required from what I can tell.  Hooks all appear to function as expected.  Reason for move to spl_autoload_register vs. __autoload() is PHP may be deprecating and removing autoload altogether.  Just so we know things will still be fine, this is being moved.
