Instead of everyone overriding save_to() and set_property() and doing a pretty asymmetric job of implementing the various properties, let's add a bit of structure here. Object properties are now represented by a Core::Property. Properties are registered with a getter and setter (optional) in constructors. I've added some convenience macros for creating and registering properties, but this does still feel a bit bulky. We'll have to iterate on this and see where it goes.
