3Delight ROP update
Several new updates have been made on 3Delight ROP. Firslty we have added a new ROP node for Standin. Changed the UI of the render settings. Removed dropdown to select render modes and instead we are using buttons to start a render. Removed lights to render from the Scene Elements, since we are following Hydra methodology by not hiding lights on the renderer when disabling it from the network. Also changed Outputs menu, Image layers and Overrides too.
