Dynamically extend other objects with AddOns

py-AddOn classes are like dynamic mixins, but with their own private attribute and method namespaces. A concern implemented using add-ons can be added at runtime to any object that either has a writable dict attribute, or is weak-referenceable.

AddOn classes are also like adapters, but rather than creating a new instance each time you ask for one, an existing instance is returned if possible. In this way, add-ons can keep track of ongoing state. For example, a Persistence add-on might keep track of whether its subject has been saved to disk.
