Ticket status change

Redirect to tickets listing page when a ticket is resolved or closed via status change.
The wording of this message cannot be reworded for translators. It needs to read:
```php
sprintf(__('%1$s Tickets — %2$s selected'), 
    TicketStateField::getVerb($state),
    $count);
```
so that the phrase can be written properly for a target language other than English
