DocumentWorkflow no longer accessible via RMI [with patch]

For some reason, the DocumentWorkflow interface has been changed to extend WorkflowContextAware, which is not RMI-capable.

Also, the added method triggerAction(WorkflowAction) is lacking a declared RemoteException.

As a result, it is no longer possible to use the DocumentWorkflow in an out-of-vm context. When you try to, you get this exception when retrieving the workflow from the WorkflowManager:

javax.jcr.RepositoryException: Problem creating workflow proxy
