I should be able to declare the List format for my Model

Summary: That is, it would be really useful to be able to say, "When showing a List of Recipes, show them like this".

The problem this is solving is that, while we have a well-established way to control how to display a given Thing (Default View), we have no way to control how to display a collection of Things. So we always have to write that at the point of call.

Thus, this probably should be a new Default Collection View property, or something like that. It should be a Property on the model, not the Instances. (Do we yet have a way to hint to the Model Designer that this Property belongs on the Model? If not, add that.)

This should default to Summary -> _bulleted, I believe.

This is actually a prequel feature to enhancing Querki Explorer -- we should automatically be applying this any time the output of the QL expression is a List of Things, which is often going to be the case in Explorer.
