web: application wizard refactor & completion
This commit refactors the various components of the Wizard and ApplicationWizard, creating a much more maintainable and satisfying Wizard experience for both developers (i.e, *me* and *Jens* so far), and for the customer. The Wizard base has been refactored into three components: **AkWizardController** The `AkWizardController` provides the event listenters for the wizard; it hooks them up, recevies the events, and forwards them to the wizard. It unwraps the event objects and forwards the relevant messages contained in the events. It knows of three event categories: - Navigation requests (move to a different step) - Update requests (the current step has updated the business content) - Close requests (close or cancel the wizard). **ak-wizard-frame** The `ak-wizard-frame` is the ModalButton interface. It provides the Header, Breadcrumbs (nee` "navigation block"), Buttons, and a DIV into which the main content is rendered. **AkWizard** `AkWizard` is an *incomplete* implementation of the wizard. It's meant to be inherited by a child class, which will implement the rest. It extends `AKElement`. It provides the basic content needed, such as steps, currentStep (as an index), an accessor for the step itself, an accessor for the frame, and the interface to the `AkWizardController`. **ApplicationWizard** The `ApplicationWizard` itself has been refactored to accommodate these changes. It inherits from `AkWizard` and provides the business logic for what to do when a form updates, some custom logic for preventing moving through the wizard when the forms are incomplete, and a persistence layer for filling out different providers in the same session. It's simplified a *lot*. The types specified for `AkWizard` are pretty nifty, I think. I could wish the types being passed via the custom events were more robust, but [strongly typed custom events](https://github.com/lit/lit-element/issues/808) turn out to be quite the pain in the, er, neck. As it is, the `precommit` pass did very good at preventing the worst disasters. The steps themselves were re-written as objects so that they could take advantage of their `valid` and `disabled` states and provide more meaningful buttons and labels. I think it's a solid compromise, and it moved a lot of display logic out of the core `handleUpdate()` business method. The tests, such as they are, are passing.
