Adding support for SonicMQ Multipart messaging Over SOAPUI

Currently we have a requirement to test Multipart message of SonicMQ Over SoapUI. In this, we are using content-partied for retrieving the message from SonicMQ server. As SOAPUI 4.0 does not support the Multipart message testing we are unable to assert the individual parts of the message. Hence It would be nice if next version of SoapUI could provide support for multipart message testing.

Thank you.
