Add "find()" method for GameObjects

[patschreiber]

Should look in each container to find a game object by an id.

GameObject.find(10) => Returns the GameObject and optionally which container it was located in.
GameObject.find(10).container (?)
GameObject.find(10, "debug") (?)

Returns the GameObject or a hash depending on if you want the debug info or not

GameObject.find(10, "debug");

// Output
{
  gameobject: GameObject,
  container: "container name"
}

Stretch Goal. Make this generic and part of the tooling for the engine. .find() can find any active instantiated object (texture, GameObject, Component, etc.)
