Add a class that is derived from object which has extra members pertinent to controllable objects. Add names to the dummy objects.
Using the work that was done in the previous commit, we now add some more information to the newly added ControllableObject. For now it primarily just extends the base Object class by a name, hit points (== health) and hunger (== food). The last one being slightly misleading in name.
The two ControllableObjects, now named “Foobert” and “Bart” also get their name rendered in the simulation mode as opposed to just drawing their object id.
