Use of addslashes in assignment/lib.php

When using MSSQL, magic_quotes_sybase gets set to on, which changes the behavior of addslashes. This is already a known issue, I'm assuming, by the function addslashes_js() and associated comments defined in lib/weblib.php.

This caused incorrect JavaScript generation in mod/assignment/lib.php on line 726 (or so) where addslashes is used to escape a generated link, which would then result in the browser throwing JavaScript errors.

To fix:

In mod/assignment/lib.php, on line ~726:

• Change 'addslashes' to 'addslashes_js'
