ZF-3104: Zend_Rest_Server::fault() should return a Zend_Rest_Server_Fault

Description

Zend_Rest_Server::fault() should return a Zend_Rest_Server_Fault in the same way Zend_XmlRpc_Server:fault() returns an Zend_XmlRpc_Server_Fault.

Comments

The entire fault response for Zend_Rest will be refactored in 2.0. Until then, an alternate method for RESTful services will be provided. This will be fixed, but not until 2.0 and then in a sweeping refactoring.
