API should allow for moving around arbitrary objects

[Winter-Guerra]

A generalized API struct similar to the "Window" struct currently in use should be created for manipulating arbitrary game objects spawned from arbitrary Prefabs.

The suggested type to add:

    public class GameObject_t
    {
        public string ID { get; set; } # instance ID
        public string prefabID { get; set; } # Prefab name for spawning new instance
        public IList<float> position { get; set; }
        public IList<float> rotation { get; set; }
        // Metadata dictionary with string key and string data.
        public Dictionary<string, string> metadata { get; set; }
     }

This should replace the "Window_t" type currently in use.

As of v1.5.4, any gameobjects that have been baked into the FlightGoggles binary can be instantiated and moved around.
