[permissions] What should "retrieve the permission state" do for pickers? (#8)

We need use cases for that in order to start extending the algorithm to include it. My first thoughts would be that pickers and permissions are opposed: if you have a picker, you probably have no associated permission.

If I had to make a pure theoretical excercise and try to have pickers fit in the current model, I think it should be something like ```granted``` the reason being that ```prompt``` will send the wrong signal to the web page, making it think the permission can be ```granted``` by the user.

This said, the only picker commonly used on the web is for <input type=file> and having a permission associated with that doesn't sound right.
