WorkFlow: the `get_ticket_changes` and `apply_action_side_effects` methods of the ITicketActionController interface, like the `render_ticket_action_control` one, where intended to be called only on the controllers that actually declared to handle the `action` being performed.

WorkFlow: enhanced the documentation and a few formatting cleanups.

In particular, I felt the need to clarify ''state'' vs. ''status''.
In many places, we were talking about ticket states referring to the ticket state as a whole, not only to its ''status'' field. The `ITicketActionController.get_all_states` method on the other hand was about getting the different values for the ''status'' fields, so I renamed the ITicketActionController method to `get_all_status`.
