Replace assign_by_ref with assign

[eileenmcnaughton]

Overview

Replace assign_by_ref with assign

Before

$smarty->assign_by_ref()

After

$smarty->assign()

Technical Details

This continues the effort to replace assign_by_ref which smarty5 discontinues with assign

Note that we have never found a case where assign_by_ref is used in a way that would not work with assign & in fact in smarty3 we actually convert it to assign anyway
