tep_not_null update using get_object_vars

When $value is an object then we have to check if it has object vars because according to PHP manual "Objects with no properties are no longer considered empty."  http://us1.php.net/manual/en/function.empty.php

So is_null($value) when $value is an object it always return false. So the appropriate way to check is using get_object_vars which will return newProp, but the protected and private members will not be returned.
added isset($SID) to tep_href_link

added isset($SID) to tep_href_link so not to provide: Notice: Undefined variable: SID in...

I know notices are not shown is osCommerce because of :

error_reporting(E_ALL & ~E_NOTICE);

but that does not mean that we don't have to check for those.
