Persistent Aircraft State

When you exist the sim and resume the flight at a later date the entire aircraft state is now saved automatically. This means even if you have to close the app or shutdown your PC you can still continue your flight as if nothing happened at a later point in time.

Aircraft Flight Model Improvements
