DeployedBy and DeployedByID properties have no effect when creating a new Deployment

[Cirzen]

Within the DeploymentResource object, the DeployedBy and DeployedByID properties both have public getters and setters.
However, setting these values has no effect on the resulting object returned from the API, they always switch back to (I'm assuming) the user whose API key has been used.
This was causing us an issue when creating child deployments: a user created the parent deployment which was stamped with their login details, but as a service account is used to create the child deployments, it is difficult to determine who launched them when reviewing logs.
If these properties have no effect on the resultant deployment resource, they should be labelled "Output Only" or similar, or have the setters made private.
