osTicket> Show “Closed Ticket” note

This is a simple mod that you can do in order to tell who closed and reopened a ticket:

include/class.ticket.php
Inside of the function close(){ information just above the return line add the following:

$this->postNote('Ticket Closed');
return (db_query($sql) && db_affected_rows())?true:false;

Then repeat the step down in the function reopen(){

$this->postNote('Re-Opened Ticket');
return (db_query($sql) && db_affected_rows())?true:false;

Now any time someone closes a ticket or reopens a ticket an "Internal Note" will be created stating either "Ticket Closed" or "Re-Opened Ticket" as well as by whom and when.
