Title: Allow capability to set content type on message being marshalled

Commits speak for themselves. We were having some [issues](https://jira.springsource.org/browse/AMQP-222) while using oxm to produce XML messages that are eventually routed to an old JMS queue with a consumer that handles messages based on contentType. This converter was basically using application/octet-stream which was causing problems in the legacy system. This change solved our problem while alloying a degree of flexibility.
