[BREAKING] Change up cell selection.

In the PrisonerManager you can now provide either AnyCell or NoCell and
it'll select a cell or not based upon the provided one. This is breaking
because it changes the required types in the methods and the new cells
don't have anything implemented and throw exceptions.
