Error in text when denying petition.

When a petition is denied, the text shown is:

"Petition is now read only (status=%1$s)"

(the "%" and "$" symbols are shown to the user).

We think that the petition status is not assigned in CoPetitionsController.php :

$this->Flash->set(_txt('er.pt.readonly'), array('key' => 'error'));

The string er.pt.readonly defined in lang.php has one parameter, but it's value is not passed in  this _txt invocation.

A possible solution for displaying the correct message could be:

$this->Flash->set(_txt('er.pt.readonly',array(_txt('en.status.pt',null,$status))), array('key' => 'error'));
