Improves Controller and Adapter relationship

- Controllers that have adapters are AdaptableControllers
- AdaptableController is responsible to instantiate the proper adapter if needed (string, function or BaseAdapter)
- BaseAdapter is the base class for adapters, allows skipping when passed directly to the controller
