Feature request title:
Flight crew swap/change
When a plane arrives the crew should be swapped / changed. That would also mean that we should be able to create / change the crews clothing like with liveries, so it can be changed according to the airlines colouring.
This will probably need to be developed together with the family option, so crew will stick together while moving over the airport.
Specific crew staff rooms are then also necessary, per airline or airline group or generic for smaller airports.
Why it should be implemented:
For game realism as planes now come and go without any crew change, which is a bit unrealistic when they just flew 10+ hours to reach your airport and just take off again after 4 hours of turnaround.
