Added a new flag in messages to know if they came from a filter or from the original chain of recipients. To do this, we've added a new way to process message filters: instead of pre-adding filters to the list of message recipients, we process filters in the Manager::pumpQueue() member function itself. (So the list of "recipients" is not modified.)
