Smarty3 expected to be a reference, value given

[gigamaster]

Smarty plugins/resource.db.php seems to have a problem with its 3rd argument, which is a reference.

Remove & from &$smarty to solve the issue.

function smarty_resource_db_timestamp($tpl_name, &$tpl_timestamp, &$smarty)`

to

function smarty_resource_db_timestamp($tpl_name, &$tpl_timestamp, $smarty)
