Add MessageSendingOperations for JMS

Browse Source 
This commit adds a JMS implementation of MessageSendingOperations,
allowing to send JMS messages using Spring's standard Messaging
abstraction.

MessagingMessageConverter is a standard JMS's MessageConverter that
can convert Spring's Message to JMS message and vice versa. Existing
infrastructure has been updated to use this implementation.
