receiveMessage() method

This method does not work correctly as written because
the connection is never started. It should have
mTopicConn.start();
inserted as the first line inside the try-block.

(This is consistent with the registerListener method,
which also starts the connection--see line 3 on page 346.)

The downloadable code, 9780596001520examples.zip, suffers the
same error.

AUTHOR: Not strictly a bug - the example just assumes that the connection is started
elsewhere. But since there's no harm (except time) in re-starting a started
queue, I added the calls the reader suggests to the receiveMessage() methods in
PTPMessagingClient and in PubSubMessagingClient.
