Please allow properties inside deploymentEnvironment

[dgutson]

Could you please allow this:

workspace {

    model {
        deploymentEnvironment singleNode {
            properties {
                nwdiag.networks "net1, net2"
            }
         }
    }
}

..or, even better, allow a networks keyword inside deploymentEnvironment.
