Gate slots - auto-scheduler

Auto-scheduler re-work

Instead of having the auto-scheduler work like we have it today, i propose we have another system in place. There should be a slot object that you can plop onto the flight planner, where you can choose what airline you want in it. These slots will stay forever, until removed by the player. Whenever an airline company gives you a flight, and there is a slot available, it should fill into that slot automatically
