Added option com.openexchange.spamhandler.cloudmark.wrapMessage to file 'spamhandler_cloudmark.properties' accepting the values true and false. If set to true the spam/ham message get propagated as a nested message to the Cloudmark service to improve Cloudmark performance.

Default is true. However, this option needs to be clarified with your running Cloudmark service that passing the spam/ham message as a nested message is accepted and properly handled!

Moreover existing deployments should not be touched and further use the mechanism in place.
