Revision 418550

Added a new/highly refactored version of the STOMP protocol implementation.

The biggest difference between this and previous implementation is that conversion between the STOMP protocol and 
the ActiveMQ protocol happens at a Transport Filter layer instead of doing it all at the WireFormat layer.

I think this has resulted in cleaner code since there's a better seperating between marshalling/unmarshalling of 
the STOMP protocol and converting the stomp protocol to the activemq protocol.
