* Implemented a new option in settings: Default start type for Player flights.
* Updated changelog.
* Removed unnecessary country parameter.
* Restore missing parameter
* on_pilot_changed should emit pilots_changed in its finally block, otherwise the start-type isn't updated if you have a single client pilot which you switch to a non-client pilot.
Also implemented other changes suggested by @Raffson, such as a more streamlined start_type QComboBox handling and moving the pilots_changed Signal to FlightRosterEditor.
* Decouple Signal from QFlighStartType
