Visualise the raw content of exchanged messages

[rbertucat]

The raw content of exchanged messages is extracted and exposed in the test execution context by the underlying step’s messaging handler. All such context information is then available for full inspection through the testbed’s user interface (GITB-UI) both for the current test run but also for recorded ones.

It is not possible to copy text from the displayed message contents. This capability would be of significant benefit.
